In which stage does dna replication occur
Web29 okt. 2024 · 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 the double helix provided a hint as to how DNA is copied. Recall that adenine nucleotides pair with thymine nucleotides, and cytosine with guanine. WebIt has been hypothesized that the high-affinity binding of the DNMT1 to un-repaired lesions in DNA could sequester available enzyme away from the replication fork and promote passive replication-dependent demethylation. 20 It has also been hypothesized that when DNA lesions occur within the promoter region of cancer-promoting genes, the aberrant …
