WebCyclin B is a member of the cyclin family. Cyclin B is a mitotic cyclin. The amount of cyclin B (which binds to Cdk1) and the activity of the cyclin B-Cdk complex rise through the cell cycle until mitosis, where they fall abruptly due to degradation of cyclin B (Cdk1 is constitutively present). The complex of Cdk and cyclin B is called maturation promoting … WebCDK1 is an essential member of the CDK family and its sequence is highly conserved across eukaryotic species. It is required for successful completion of mitosis. Mitosis is …
