Cell And Molecular Biology

Students will –

CO77: Examine the structure and function of biomembrane and its role in active and passive transport.

CO78: Elaborate the role of Cytoskeleton, Cell Junctions and cellular adhesion molecules in intracellular movements and cell to cell and cell to matrix interactions.

CO79: Acquire the detailed knowledge of different pathways related to cell signaling and apoptosis thus enabling them to understand the importance of cell cycle regulation checkpoints.

CO80: Perceive the detailed knowledge about chromosomal organization of genes and noncoding DNA.

CO81: Conclude the role of DNA binding motifs in regulation of gene expression.
