In eukaryotic cells, the cell cycle is divided into two major phases: interphase and mitosis (or the mitotic (M) phase). Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells. early 2000\u0027s club hits

WebThe DNA will then be zipped back up, and the cell will move into Gap 2. All of the DNA replication happens during interphase; therefore, no DNA is replicated during meiosis. Meiosis's goal is to ... WebReplication forks are formed at each replication origin as the DNA unwinds. The opening of the double helix causes over-winding, or supercoiling, in the DNA ahead of the replication fork. These are resolved with the action of topoisomerases. Primers are formed by the enzyme primase, and using the primer, DNA pol can start synthesis.
