Witryna15 cze 2016 · DNA replication occurs before mitosis. Explanation: Mitosis is the process of nuclear division of cells and is part of the cell cycle. As you can see in the image below, DNA replication takes place in the S-phase of the cell cycle, which is before the cell enters mitosis. WitrynaInterphase has three sections. The G 1 (first gap) phase is the interval between mitosis and the onset of DNA replication. The S (synthetic) phase is the time when DNA is replicated. The G 2 (second gap) phase is the interval between the termination of DNA replication and the onset of mitosis. In multicellular organisms, many differentiated ...

WitrynaThe 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. WitrynaDuring mitosis one cell divides before on form two identic cells. The major purpose of mitosis belongs by achieving additionally to replace haggard out cages.
