- Which of the following statements is true regarding cell cycle regulators?
Choose 1 answer:
- Different cyclins send a Cdk to different targets.
- Levels of cyclins do not change dramatically across the cell cycle.
- When a cyclin partners with a Cdk, it inactivates the Cdk.
- A Cdk is a DNA repair enzyme.
Homework Answers
In this case, the union between cyclins and Cdk has two main functions:
1)The activation of the kinase activity of the Cdk
2)Sending Cdk to specific target proteins. This will depends on the cell cycle stage.
So, the correct statement is Different cyclins send a Cdk to different targets.
