Individual cells reproduce through the processes of mitosis and meiosis. Both mitosis and meiosis have two key components - division of the genetic material (usually accomplished through prophase, metaphase, an
Background: Cytokinesis occurs just as chromosomes complete segregation and reform nuclei. It has been proposed that cyclin/Cdk kinase inhibits cytokinesis until exit from mitosis; however, the timer of cytokinesis has not been experimentally defined. Whereas expression of a stable version of Drosophila...
The lowest NDI value possible is 1.0, which occurs if all of the viable cells have failed to divide during the cytokinesis-block period and are therefore all mononucleated. If all viable cells completed one nuclear division and are therefore all binucleated, the NDI value is 2.0. An NDI val...
Which phase of mitosis (prophase, metaphase, anaphase, or telophase) does a dividing cell spend most of its time in? Cytokinesis usually occurs: a) during interphase. b) after telophase. c) during anaphase. d) at the same time as telophase. ...
Endoreduplication is a variant of the cell cycle in which the nuclear genome is replicated but not gone through mitosis or cytokinesis, resulting in polyploidy (Sugimoto-Shirasu and Roberts, 2003). Endoreduplication usually occurs in the quickly developed or differentiated tissues, which have high met...
Cytokinesis usually occurs: a) during interphase. b) after telophase. c) during anaphase. d) at the same time as telophase. In which stage of mitosis do tubulins assemble into spindle microtubules? a. prophase b. prometaphase c. ...
This coiling towards the two spindle pole bodies leaves the Rap1-enriched telomere repeats trapped at the septum between mother and daughter cell; chromosome breakage occurs by septum formation and thus eliminates the telomere-to-telomere dicentric fusions that arose before mitosis [20•]. A ...
Plant cell and animal cell are both eukaryotic, and both divide themselves through the mitosis cell cycle. In these cells, DNA replication takes place first, then nuclear division occurs, and finally, the cell divides itself into two new cells. Answer...
