Cell Biology

The students will-

 

CO6: Analyse the functions of nucleus and extra nuclear organelles and understand the intricate cellular mechanisms involved.

CO7: Appraise the detailed knowledge of different pathways related to cell signalling and apoptosis thus enabling them to understand the anomalies in cancer

CO8:Develop an understanding about how cells work in healthy and diseased states and to give a ‘health forecast’ by analyzing the genetic database and cell information.

CO9: Investigate new avenues of joining research in areas such as genetic engineering of cells, cloning, vaccines development, human fertility programme, organ transplant, etc.

CO10: Develop an understanding how tissues are produced from cells in a normal course and about any malfunction which may lead to benign or malignant tumor.

CO11: Differentiate and evaluate the role of different cytoskeleton components in intracellular movements and intercellular interactions.
