Following replication, each chromosome now consists of two sister chromatids (see figure below). Thus, the amount of DNA in the cell has effectively doubled, even though the ploidy, or chromosome count, of the cell remains at 2 n.

WebMitosis occurs in all somatic (body) cells. There are four phases of mitosis (PMAT) ~ 1) Prophase 2) Metaphase 3) Anaphase 4) Telophase During prophase, the chromosomes form, and the nuclear envelope and the nucleolus are no longer visible. WebDiscuss Concepts Eukaryotic chromosomes can be labeled by exposing cells to radioactive thymidine during the S phase of interphase. If cells are exposed to radioactive thymidine during the S phase, would you expect both or only one of the sister chromatids of a duplicated chromosome to be labeled at metaphase of the following mitosis (see Section … income release switch on form
