webMar 17, 2022 · 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.

webJun 1, 2020 · Definition. DNA replication is a process that occurs during cellular division where two identical molecules of DNA are created from a single molecule of DNA. As a semiconservative process, a single molecule containing two strands of DNA in double helix formation is separated, where each strand serves as a template for the new DNA molecules.

webThe 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 the double helix provided a hint as to how DNA is copied. Recall that adenine nucleotides pair with thymine nucleotides, and cytosine with guanine.
