Molecular biology is the study of biological activity at the molecular level, focusing on the interactions and synthesis of DNA, RNA, and proteins within cells.
While closely related, molecular biology primarily focuses on the molecular mechanisms of gene expression and cellular processes, whereas genetics broadly studies heredity and variation in living organisms.
The core molecules studied are DNA (deoxyribonucleic acid), RNA (ribonucleic acid), and proteins, which are fundamental for storing genetic information and performing cellular functions.
Common techniques include PCR (Polymerase Chain Reaction), gel electrophoresis, DNA sequencing, gene cloning, CRISPR gene editing, and Western blotting for analyzing molecules.
