Cell Division: Mitosis and Meiosis · Zoology

Which molecule inhibits CDK activity to regulate cell division?

  1. Cyclin, the CDK-activating partner
  2. Tubulin, the spindle building block
  3. CDK inhibitor proteins
  4. Histone, the DNA-packaging protein
Show answer and explanation

Correct answer: CDK inhibitor proteins

CDK inhibitor proteins bind to cyclin-CDK complexes and suppress their activity. This helps control proper timing of cell division.
