WebMar 16, 2024 · 9.2: DNA Replication. When a cell divides, it is important that each daughter cell receives an identical copy of the DNA. This is accomplished by the process of DNA replication. The replication of DNA occurs during the synthesis phase, or S phase, of the cell cycle, before the cell enters mitosis or meiosis. The elucidation of the structure of ... Semiconservative replication describe the mechanism of DNA replication in all known cells. DNA replication occurs on multiple origins of replication along the DNA template strand (antinsense strand). As the DNA double helix is unwound by helicase, replication occurs separately on each template strand (sense strand) in antiparallel directions. This process is known as semi-conservative replication because two copies of the original DNA molecule are produced, each c…
