Question

1. a cell going through the cell cycle that failed to complete dna replication would most likely get stopped at this checkpoint. 18. this checkpoint looks for cell size and growth factors. 19. what happens to a cell that gets stopped at the g1 checkpoint?

Explanation:

• Question 17: The \(G_2\) checkpoint checks for DNA replication completion. If DNA replication fails, the cell cycle stops at \(G_2\).
• Question 18: The \(G_1\) checkpoint assesses cell size and the presence of growth factors.
• Question 19: A cell stopped at the \(G_1\) checkpoint enters the \(G_0\) phase (quiescent state).

Answer:

1. \(G_2\) checkpoint
2. \(G_1\) checkpoint
3. Enters \(G_0\) phase.
