DNA Replication

DNA Replication The Blueprint of Cellular Continuity DNA replication is a fundamental biological process by which a cell copies its entire genetic material before division. It ensures that each daughter cell receives an exact duplicate of the parent cell’s DNA , thereby preserving genetic integrity across generations. This highly orchestrated mechanism is essential for growth , development , tissue repair , and reproduction in all living organisms. At its core, DNA replication is semi-conservative—meaning each new DNA molecule consists of one original strand and one newly synthesized strand. The process involves multiple enzymes and protein complexes that act with extraordinary precision to prevent errors that could result in mutations or genetic disorders . It occurs during the S phase of the cell cycle and is tightly regulated to ensure fidelity. Studying DNA replication provides insight into broader topics such as genetic inheritance , molecular biology , oncogenesis ...
