ZOO505 : Cell and Molecular Biology

Course Overview

Course Synopsis

This course will help students to understand the building blocks of life "The cells", how they made up of, cell constituents, cell interaction, cell processes as well as it will explore basic concepts about molecular biology topics starting from nucleic acids (DNA and RNA), genes, genome and then finally up to the gene expression level.

Course Learning Outcomes

Learning this course will help students to get a through understanding of common cellular and molecular processes of body in relation to different body functions.

  • This course will impart knowledge about the animal cell and its complex organization of architecture
  • It will provide understanding about the unified role of a cell for the ultimate sustainability of the organisms.
  • Enable students to understand various ultra-structural, molecular and functional aspects of the cells will be communicated in this course
