Webnoun plural sister chromatids : either of the two identical chromatids that are formed by replication of a chromosome during the S phase of the cell cycle, are joined by a centromere, and segregate into separate daughter cells during anaphase WebBoth mitosis and meiosis are associated with cytokinesis. Passage through mitosis is driven by precisely-timed changes in transcriptional regulation and protein degradation. Dynamic control of protein phosphorylation is necessary for the regulation of many cellular processes, including mitosis and cytokinesis.

Webcytokinesis [ sahy-toh-ki- nee-sis, -kahy- ] noun Cell Biology. the division of the cell cytoplasm that usually follows mitotic or meiotic division of the nucleus. There are … WebThe final phase of cell division, in which membranes form around the two groups of chromosomes, each at opposite ends of the cell, to produce the two nuclei of the daughter cells. The spindle disappears, and the cytoplasm usually divides (in the process called cytokinesis). In mitosis, telophase is preceded by anaphase. WebCytokinesis, the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis. It may start in either anaphase or telophase, depending on the cell, and finishes shortly after telophase. In animal … dachshund for sale in arizona
