HOD Desk


Mr. Bimal Chandra Gogoi
HOD, Botany
The Department of Botany, Namrup College is one of the well equipped department in the college. It has been imparting the teaching on B. Sc major and core courses in the subject Botany under the academic curriculum of Dibrugarh University. Apart from B. Sc course, department is also running different certificate and vocational courses like Certificate in Herbal Medicine, Certificate course in Bio-technology and Vocational course on Tea-Plantation and Management. Two minor research projects were undertaken and one mega research project is going on.
                  However the Biology subject was started since the year 1973 in the College. The Degree course in Biochemistry was started in 1987 session as core course. The major course in Botany was opened in the year 1993, just after getting "deficit grant-in-aid" by the science stream. The Science stream of Namrup College was brought under the Deficit Grant-In–Aid on 14th July of 1992.
                  There was a single laboratory room for all practical classes for all science subjects in the present day chemistry laboratory. The office room of the college at that time was converted into Botany lab in 1987. Now it is running with little modifications. The college office was shifted to another room.
                   Before my appointment the Botany practical was taught by temporary teachers,
sometimes by the Zoology teacher Mrs. Dipalee Dutta Bordoloi.  From 1986 to 1990 Botany department was run by single Teacher with a single Bearer. Present principal of Namrup College, Dr. Jitu Buragohain was appointed as Lecturer in the department of Botany in the year 1992. Initially there were three sanction posts of teaching faculty. But at present only two faculty members are working in the department and one post is still vacant. At present, there are two well experienced Bearers in the department.
              We feel proud of being a faculty of this department of Namrup College.

Nucleoproteins


            Nucleoproteins are any proteins that are structurally associated with nucleic acids, either DNA or RNA. Typical nucleoproteines include ribosomes, nucleosomes, and viral nucleocapsid proteins.
Deoxyribonucleoproteins
            A deoxyribonucleoprotein (DNP) is a complex of DNA and protein. The prototypical examples are nucleosomes, complexes in which genomic DNA is wrapped around clusters of eight histone proteins in eukaryotic cell nuclei to form chromatin. Protamines replace histones during spermatogenesis.

Ribonucleoproteins

            A ribonucleoprotein (RNP) is a complex of RNA and protein. The enzyme telomerase, vault ribonucleoproteins, RNase P, hnRNP and small nuclear RNPs (snRNPs), and ribosomes are ribonucleoproteins. Ribosomes consist of one molecule of each of 50 or more ribosomal proteins along with three different molecules of RNA in prokaryotes or four in eukaryotes.
            Some viruses are simple ribonucleoproteins, containing only one molecule of RNA and a number of identical protein molecules. Others are ribonucleoprotein or deoxyribonucleoprotein complexes containing a number of different proteins, and exceptionally more nucleic acid molecules.
Functions-
            In eukaryotic cells, DNA is associated with about an equal mass of histone proteins in a highly condensed nucleoprotein complex called chromatin. Deoxyribonucleoproteins in this kind of complex interact to generate a multiprotein regulatory complex in which the intervening DNA is looped or wound. The deoxyribonucleoproteins participate in regulating DNA replication and transcription.
            The ribonucleoproteins play a role of protection. mRNAs never occur as free RNA molecules in the cell. They always associate with ribonucleoproteins and function as ribonucleoprotein complexes.
            In the same way, the genomes of negative-strand RNA viruses never exist as free RNA molecule. The ribonucleoproteins protect their genomes from RNase. Nucleoproteins are often the major antigens for viruses because they have strain-specific and group-specific antigenic determinants.
Structure-
            Through crystallographic methods, the specific spatial structure and biological functions of many nucleoproteins are understood. The structures of many viral nucleoproteins have been determined, including those of influenza, rabies, Ebola, Bunyamwera, Schmallenberg, Hazara, Crimean-Congo hemorrhagic fever and Lassa. Important techniques for detecting the structures of nucleoproteins include X-ray diffraction, nuclear magnetic resonance and cryo-electron microscopy.
Classification of nucleoprotein-
1.      Histones – These are very basic proteins, basic because they are enriched in the amino acids arginine and lysine to a level of about 24 mole present. arginine and lysine at physiological pH are cationic
and can interact electrostatically with amionic nucleic acids. thus, being basic, histones bind tightly to DNA which is an acid. there are 5 types of histones in the eukaryotic chromosomes, namely H1, H2A, H2B, H3 and H4

2.   Non-histones-about 50% non-histones of chromatin have been found to be structural proteins and include such proteins as actin, and α- and β-tubulins and myosin. They vital ingredients of the chromosome, functioning during chromosome condensation and in the movement of chromosomes during mitosis and meiosis. many of the remaining 50%of the non-histones include all the enzymes and that are involved in DNA replication, in transcription and in the regulation of transcription. These proteins are not a highly conserved among organisms, although they must carry out similar enzymatic activities. Apparently they are not as important as the histones in maintaining chromosomes integrity.  

Tell me why?


Slowly but surely                                                                                          Sahadev Sah
      I have noticed that                                                                                   B. Sc 4th Semester
She has stopped calling me                                                                           Dept. of Botany
  And neglecting me…..
I don’t understand why?
      Why she behaving with
                  Such a way on
I am trying to find out
Whether I did any gaffe
But very miserably
I don’t find any clue
         So I feel much glad
When I remember the past
   Those cheerful days were
When I was with you
Still rhythmic sensation of my heart
I think about the past
My heart cries a lot
You have elapsed me
I want to know why this with me?
        But I can’t, I could
 I can’t forget you beloved
           Your kind heart
Your sweet smile

        And your friendly face….

ASSAM TEA

             
Abhijit Baruah, B. Sc 4th Sem,
Botany Major
Tea has become almost universal in use because many people all over the world now-a-days drink tea. Tea is made from the leaves of the tea-plant. This plant is an evergreen shrub. 
Tea was first cultivated in china. Now-a-days along with china, India and Srilanka are also two large producers. In India, Assam and Darjeeling are the best areas for tea plantation.
            Tea plants grow well on the slopes of the hills where there is much rainfall as well as sunshine. It requires 70F to 80F. Water should not be logged at the roots. The tea plant grows best on the sloping hill-sides.
Tea leaves are plucked from the plants about four times a year in April, May, June and August.
There are different qualities of tea. The buds and young leaves make the best kind of tea. The larger and older leaves do not make good tea.
            Assam tea is a black tea named after the region of its production. Assam tea is manufactured specially from the plant Camellia sinensis var. assamica. This tea most of which is grown at or sea level is known for its briskness, malty flavor, and strong, bright colour.
The state of Assam is the world’s largest tea growing region, lying on either side of the Brahmaputra River, and bordering Bangladesh and Myanmar.             This part of India experiences high precipitation during the monsoon period as much as 10 to 12 inch of rain per day.
Historically Assam has been the second commercial tea production region after Southern China. Southern China and Assam are the only two regions in the world with native tea plants. 


The gardens in Assam do not follow the Indian standard time which is the time observed throughout India and Srilanka. The local time in Assam tea garden known as “Tea Garden Time” or Bagantime. Working time for laborers in the gardens is generally between 9 a.m. to 5 p.m. It may vary slightly from garden to garden.
            The tea plant is grown in the lowlands of Assam. The Assam tea bush grows in a lowland region, in the valley of the Brahmaputra River. Each year the tea estates of Assam collectively yield approximately 1,500 million pounds (680,400,000kg) of tea.
Assam tea is generally harvested twice in a “first flush” and a “second flush”. The first flush is picked during late march. The second flush, harvested later  is the more prized “tippy tea”. This second flush tippy tea is sweeter and is generally considered superior to the first flush tea.
            The leaves of the Assam tea bush are dark green and glossy and fairly wide compared to those of the Chinese tea plant.

National Science Day

Prof. Sanjay Seal & Prof. Asifa Subhan
           National Science Day is celebrated all over India with great enthusiasm on 28th of February every year in order to commemorate the invention of the Raman Effect in India by the Indian physicist, Sir Chandrasekhara Venkata Raman on the same day in the year 1928. For his great success in the field of science in India, Chandrasekhara Venkata Raman was awarded and honored with the Nobel Prize in the Physics in the year 1930.

History of National Science Day Celebration in India-

            28th of February, 1928 was the great day in India when an invention in the field of Indian science was completed by the famous Indian physicist, Sir Chandrasekhara Venkata Raman. He was a Tamil Brahmin and first one in the science, who had researched such invention in India. To commemorate and honor this event always in the future, 28th of February was asked to the Indian Government to designate as a National Science Day in India by the National Council for Science and Technology Communication (NCSTC) in the year 1986.
            From then, the national science day was started celebrating all across the India as a great event in the field of Indian science. It is celebrated every year by students, teachers, scientists and
Borgeet Song by Swarnali 
researchers in all the schools, colleges, universities, educational institution including scientific, academic, medical, technical and research institutions of India. On the first celebration ceremony of the National Science Day in India, the National Council for Science and Technology Communication had declared the institution of the National Science Popularization awards in order to recognize an excellent and wonderful endeavor in the field of science communication and popularization.
            Sir Chandrasekhara Venkata Raman had worked from 1907 to 1933 at the Indian Association for the Cultivation of Science, Kolkata, West Bengal in India during which he had researched on many topics of the Physics from which the Raman Effect (effect on scattering of light when passing through different materials) became his great success and

discovery which has been marked in the Indian history. For his big invention he was honored through the various Indian awards including the Nobel Prize in the year 1930. From the year 2013, the “Raman Effect” has been designated as an International Historic Chemical Landmark by The American Chemical Society.
            During the national science day celebration of the year 2009, the Indian Department of Science and Technology has awarded the five Indian institutions through the National Award for Science Communication in order to recognize the big efforts and achievements of the Indian scientists of the government and non-government organizations for popularizing and leading the modern science in the country. The Vikram Sarabhai Community Science Centre was given the highest award in the year 2009 to recognize its big contribution to the science.           
Quiz Master team
The national science day has been started getting celebrated as the Science Carnival to recognize scientific activities and programs by the participation of students from school and college, scientists from the state and national faculties. This event celebration has provided a real platform for various new comer scientists to fix their feet and bright their career in the science profession.
           
      This year, on 28th February 2017 we Namrup College family also celebrated National Science Day. The Socio-cultural Development Centre(SCDC) of Namrup College with collaboration of Institutional Bio-tech Hub, Namrup College were organized the Science day program with several beautiful contents and tried to popularized science day in the region.

We are, from Namrup College family wishing all best for all the participants and presented students friends.

Career in Botany

            Botany is an important branch of biological sciences which is deals study of all about, not
only plants but also numerous derivatives and products of plant. Botany covered the area from basic knowledge of plants with scientific manner to chemistry, agriculture, forestry, biotechnology, etc. Without adequate knowledge about external and internal structural and functional events of plants we cannot gist actual vastness of botany subject and its allied subjects. But one who able to gather all aspects of basics of Botany may fix his career in this field or allied branches. Careers in Botany typically require a degree in plant sciences. Botany specialties may require advanced degrees. Among the many major tracks or options in botany programs are Plant Physiology, Ecology, Plant Genetics, and Systematic and Plant Pathology.
            There are several common career options for Under and Post- Graduates students in the field of Botany. Though these are all fall under the vast umbrella of Botany subject, many of these scientific careers blend with one another in areas of study or emphasis. In addition to the following positions, research and teaching positions are also common service sector for such degree holders in where one can make his brilliant future scenario.
1.      Plant Taxonomist
Plant Taxonomists organize species of plants into categories, after studying individual plants and grouping their species together based on similarities. A lot the species that they identify are representative of the established evolutionary relationships of plant groups. The student who likes to become plant taxonomist may concentrate their study each and every matters of taxonomic related issues. There are several fields where plant taxonomist is required. Example- Botanical Survey of Inida.
2.      Agronomist
These are soil and plant scientists who work to improve the yield of field crops like grains and cotton. They develop processes that assist farmers in growing more crops and preventing disease in them. Example- Jobs in agriculture and related fields.

3.      Ecologist
These scientists study plants interactions with the environment and other organisms. They study the ecosystems of plants with the goal of protecting them and solving environmental issues. Lots of ecology base project, organization etc.
4.      Mycologist
Traditionally, mycologists study fungi and how these damaging organisms injure plant life. Mycologists may also be grouped as a type of microbiologist owing to their study of bacteria and algae as they relate to microorganisms. Example- Plant Pathologist, Jobs in ICFRI, Rubber Board, Coffee Board, Tea Board etc.
5.      Plant Breeder
Plant breeders use traditional hybridizing and crossbreeding techniques, rather than genetic engineering, to improve plants for human uses as well as the environment. Plant breeders are a type of plant geneticist, and other geneticists may work more directly with the plant genomes. Example- Jobs in Agriculture
6.      Horticulturist
These individuals cultivate, grow and care for plants, ranging from fruits to flowers. They can work
in areas such as gardens, nurseries or tree orchards. Jobs in Agriculture etc
7.      Biophysicist
Biophysicists study the physical and mechanical energy of cells and living organisms. Within plants, they can determine how applicable medicine cures plant disease. Jobs in Research Institute, Laboratory, Educational Institute etc.
8.      Teaching jobs
 In its broadest sense, teaching is a process that facilitates learning. Teaching is the specialized application of knowledge, skills and attributes designed to provide unique service to meet the educational needs of the individual and of society. The choice of learning activities whereby the goals of education are realized in the school is the responsibility of the teaching profession. Botany graduate and post graduate individual may choose carrier as teacher in different level of academic institutes including from school, college and universities.
9.      Scientist jobs
A scientist is a person engaging in a systematic activity to acquire knowledge that describes and predicts the natural world. In a more restricted sense, a scientist may refer to an individual who uses the scientific method. The person may be an expert in one or more areas of science. A student who willing to dedicate himself in researches him may go for that. There are lots of departments or organization where Botany students are serving as scientist. Such organizations are- Rain Forest Research Institute, CSIR, DST, BIS, Tea Research Institute, BSI, Rubber Board, Coffee Board, Tea Board, Silk Board etc.

Other jobs
            Besides above mentioned specific jobs, Botany degree holder can apply any kind of common jobs like IAS, IPS, IFS, SSC, IUPAC, Banking sectors etc.

If you want to learn something no one can stop you,
but if you don’t want to learn no one can teach you.
