Question

How does cell cycle regulation, particularly the role of p53, prevent damaged cells from entering S phase?

Accepted Answer

p53 halts the cell cycle in G1 phase, allowing for DNA repair or apoptosis if damage is detected.

Answer

p53 promotes the transition from G1 to S phase regardless of DNA damage.

Answer

p53 directly repairs DNA damage.

Answer

p53 accelerates the cell cycle to quickly bypass damaged DNA.
