DNA Replication
DNA, or Deoxyribonucleic acid, is the genetic material in the majority of living organisms. The process of DNA replication is a biological mechanism that generates two identical copies of DNA from an original strand. The replication of DNA occurs during the synthesis phase, or S phase, of the cell cycle, before the cell enters mitosis or meiosis. In this process, initially, an enzyme called DNA helicase unwinds the DNA molecule, leading to the separation of its strand, and enzymes known as polymerases catalyse the formation of new DNA strands. The initiation of new DNA strands occurs with the help of a small RNA primer.
DNA Replication
DNA replication is a fundamental biological process by which a cell duplicates its entire DNA. DNA is a self-replicating structure and the replication is catalyzed by enzymes. Through DNA Replication, genetic information is passed on from one generation of cells to the next during cell division. It takes place in the nucleus of eukaryotic cells and the cytoplasm of prokaryotic cells.
