WebThe stages of mitosis are: prophase, metaphase, anaphase and telophase. Only two pairs of chromosomes. are shown in the diagrams below. There are 23 pairs of chromosomes in a diploid human body cell. WebAnaphase-promoting complex. Anaphase-promoting complex ( APC) is a complex of several proteins which is activated during mitosis to initiate anaphase. The APC is an E3 ubiquitin ligase that marks target proteins for degradation by the 26S proteasome. The irreversibility of proteolysis is utilized by cells to give the cell cycle directionality.

WebAnaphase (from Ancient Greek ἀνα-() 'back, backward', and φάσις (phásis) 'appearance') is the stage of mitosis after the process of metaphase, when replicated chromosomes are … WebThe anaphase-promoting complex (APC/C) is a large ubiquitin-protein ligase which controls progression through anaphase by triggering the degradation of cell cycle regulators such as securin and B-type cyclins. The APC/C is an unusually complex ligase containing at least 10 different, evolutionarily conserved components.
