Molecular Biology is the branch of biology that deals with the study of the structure and function of the macromolecules essential for life, mainly DNA, RNA, and proteins. It focuses on understanding the interactions between the various systems within a cell, including the interrelationships of DNA, RNA, and protein synthesis and how these interactions govern cell function.
The field of Molecular Biology emerged in the mid-20th century, with foundational work beginning in the 1930s and 1940s:
