I'm not allowed by the team to add so ..I will use YouTube to communicate now
mam help me i am doing bsc and want to go for higher studies but so confused and depressed ..i dont know which books to consult...😭😭
Before looking for books to consult, please find what opportunities you have for pursuing higher studies after bsc. What msc programs are you eligible for? What are the entrance exams etc etc. Not all answers can be found in books. All the best ahead :)
Hi Mam,I also qualified with GATE BT in 2012(AIR 131) and in 2011(AIR 519).I graduated with MTech Clinical Engineering from IIT Madras in 2015.I am interested i Bioinformatics.I want to take up BINC exam.How to go about preparing for the same?
Thank you for your message. This is the first time I am hearing of BINC exam. I understand that there are three parts to this and that the third is practicals including programming. If you have no programming experience, I suggest that you start learning programming basics from unacademy as well as the grasshopper app by google. also pick up a simple language like C or Perl or python. I will get back to you if I find more nuanced information about this exam. Thank you.

  4. What is Cell Biology? The study of cells What are cells? the smallest structural and functional unit of an organisnm which is typically microscopic and consists of cytoplasm and a nucleus enclosed in a membrane basic structural, functional, and biological unit of all known living organisms "Building blocks of life" Smallest unit of life General view of cells in the growing root-tip of the onion, from a longitudinal section, enlarged 800 diameters a. non-dividing cells, with chromatin-network and deeply stained nucleoli; b. nuclei preparing for division (spireme-stage); c. dividing cells showing mitotic figures; e. pair of daughter-cells shortly after division Ilustration by E.B. Wilson, 1900, The Cell in Development and Inheritance

  5. Cell Theory Robert Hooke (1635-1707) first observed cells (cork specimen) Anton van Leeuwenhoek (observed living cells) Theodor Schwann, Matthias Schleiden, and Rudolph Virchow (proposed cell theory) - All lving organisms are composed of cells. They may be unicellular or multicellular The cell is the basic unit of life - Cells arise from pre-existing cells (They are not derived from spontaneous generation) - Robert Hooke's Robert Hooke's microscope illustration of suber cells and mimosa leaves
