Molecular and cellular biology

Molecular and cellular biology is the study of life at the smallest levels, focusing on molecules like DNA, RNA, and proteins, which are essential for the structure and function of cells. Cells are the basic building blocks of all living organisms. This field examines how these molecules interact within cells to drive processes essential for life, like growth, reproduction, and response to the environment. Understanding these mechanisms helps researchers develop medical treatments and advances in biotechnology, illuminating how life operates on a fundamental level.
