WebEukaryotic cells reproduce genetically identical copies of themselves by cycles of cell growth and division, instead of by binary fission. The cell cycle diagram shows that a cell division cycle consists of 4 stages: G1 is the period after cell division, and before the start of DNA replication. WebWhen the replication fork reaches the end of the chromosome, however, there is (in many species, including humans) a short stretch of DNA that does not get covered by an … WebIn eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase. During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells. tshock custom items
