Molecular biology

Definition

Molecular biology is a branch of biology that seeks to understand the molecular structures and chemical processes that are the basis of biological activity within and between cells. It is centered largely on the study of nucleic acids and proteins. It examines the structure, function, and interactions of these macromolecules as they orchestrate processes such as replication, transcription, translation, protein synthesis, and complex biomolecular interactions. The field of molecular biology is multi-disciplinary, relying on principles from genetics, biochemistry, physics, mathematics, and more recently computer science (bioinformatics).
