WebTogether with Wee1, M-Cdk activation is switch-like. What are the 4 stages of the cell cycle? In eukaryotes, the cell cycle consists of four discrete phases: G 1, S, G 2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. WebSep 12, 2024 · How do CDKs activate proteins? Cdk activation requires two steps. First, cyclin must bind to the Cdk. In the second step, CAK must phosphorylate the cyclin-Cdk complex on the threonine residue 160, which is located in the Cdk activation segment.
