WebAt what point does DNA replication occur and why? The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells. WebThe stage for DNA replication is set in the G1 phase of the cell cycle and DNA is synthesized in the S phase. DNA replication is initiated at specific sites in the genome known as the ‘origins’ which are recognized and bound by origin binding proteins. ...
