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. WebThe process of duplicating DNA is referred to as DNA replication. The replication process involves several proteins known as replication enzymes as well as RNA. In eukaryotic cells, such as animal cells and plant cells, DNA replication occurs during the S phase of interphase during the cell cycle.

WebSep 27, 2024 · DNA replication occurs in the S-phase of the cell cycle and is initiated by helicases, which unwind the double helix of the DNA molecule.
