Molecular and Cell Biology:
Molecular and Cell Biology (MCB) focus on the study of molecular structures and processes of cellular life and their roles in the function, reproduction, and development of living organisms. It observe the composition, structure and interactions of cellular molecules such as nucleic acids and proteins that carry out the biological processes essential for the cell's functions and maintenance.
Neurobiology is concerned with uncovering the biological mechanisms by which nervous systems mediate behavior. Increasing attention is being given to integrative or systems neurobiology .It is the study of aggregates of neurons and functional circuits.
