HideShow resource information

1. When ATM and ATR detect change, they?

  • Phosphorylate Chk1 & Chk2, which in turn phosphorylates p59
  • Phosphorylate Chk1 & Chk2, which in turn phosphorylates p53
  • Phosphorylate Chk1 & Chk2, which in turn phosphorylates p49
  • Phosphorylate Chk1 & Chk2, which in turn phosphorylates p27
