DNA Replication and Checkpoint Control in S Phase

WebIn the S phase (synthesis phase), DNA replication results in the formation of two identical copies of each chromosome—sister chromatids—that are firmly attached at the centromere region. At this stage, each chromosome is made of two sister chromatids and is a duplicated chromosome. The centrosome is duplicated during the S phase. WebA) A cell has 10 choromosomes.

WebIn a regular somatic cell (before DNA is replicated in the S phase), there are 46 chromosomes - 23 of each kind as well as their homologous opposite. I.e. - you have an 'A' chromosome (1 'A' chromatid) and an 'a' chromosome (1 'a' chromatid), 'B' and 'b', 'C' and 'c' and so on, each coming from a different parent. 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 …

WebJul 15, 2024 · As DNA replicates during the S phase to prepare the cell for mitosis, each chromatid is copied.
