Molecular biology is the branch of science that explores the molecular basis of biological activity within and between cells. It focuses on understanding how macromolecules—specifically DNA, RNA, and proteins—are synthesized, regulated, and interacted with to control cellular functions. By studying mechanisms like DNA replication, transcription into RNA, and translation into proteins (the Central Dogma), molecular biologists can uncover how genetic information dictates traits and drives life processes. This field underpins modern biotechnology, genetic engineering, and advanced medicine, offering critical insights into the root causes of diseases and the development of targeted therapies.
