Molecular Biology
Molecular biology is the branch of biology that studies the composition, structure, and interactions of cellular molecules, including nucleic acids and proteins, and how these interactions are regulated. This hub aggregates 62,000+ verified entries, research breakthroughs, and interdisciplinary connections.
Overview & Scope
Molecular biology focuses on understanding the molecular mechanisms that underpin biological processes. It emerged in the mid-20th century as a synthesis of genetics, biochemistry, and virology, evolving into a cornerstone of modern biomedical research.
Key areas of study include DNA replication, RNA transcription, protein synthesis, gene regulation, and molecular signaling pathways. The field has been revolutionized by techniques such as CRISPR-Cas9, next-generation sequencing, and cryo-electron microscopy.
