2. When ATM and ATR detect change, they?

  • Phosphorylate Chk1 & Chk2, which in turn phosphorylates p59

  • Phosphorylate Chk1 & Chk2, which in turn phosphorylates p27

3. Which of these does p53 NOT do?

  • induces expression of genes for DNA repair
  • p53 does all of these
  • induces expression of genes for apoptosis
