Molecular Biology
Molecular Biology is a branch of biology that focuses on the molecular basis of biological activity, especially the interactions between DNA, RNA, proteins, and how these molecules regulate cellular processes. Molecular Biology studies the structure, function, and regulation of genes and the molecules involved in genetic information flow, including DNA replication, transcription, translation, and gene regulation.
