Term
Four phases! + definitions
Definition
G1 (growth state), S (synthesis of DNA), G2 (growth 2 state), M (meitosis and cytokinesis)
Term
Checkpoints: G1 to S and G2 to M
Definition
G1 to S: ensures environment is suitable for reproduction, DNA is properly synthesized. G2 to M: intact and replicated DNA
Term
CDK
Definition
cyclin dependent kinase, requires cyclin binding to get activated
Term
Peaks of CDK activity?
Definition
Meitosis
Term
How to stop CDK activity
Definition
Kill the cyclin with ubiquitination (kiss of death) and then degredation. Cyclin falls off, CDK can't process
Term
S-CDK
Definition
triggers DNA rep, makes sure it is only repped ONCE
Term
