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. WebApr 9, 2024 · The process of DNA replication can be summarized as follows. DNA replication steps DNA unwinds at the origin of replication. Helicase opens up the DNA-forming replication forks; these are extended bidirectionally. Single-strand binding proteins coat the DNA around the replication fork to prevent rewinding of the DNA. circuit breaker buzzes and trips https://deltasl.com
