Question

during the g₂ checkpoint, cells verify that all dna is replicated correctly before entering mitosis. which explanation best shows why this checkpoint is essential for organismal growth?

Explanation:

The G₂ checkpoint verifies DNA replication. If DNA is replicated correctly, healthy cell growth occurs. Incorrect replication could lead to faulty cells. The option "It helps ensure new cells have complete, error - free DNA, supporting healthy growth" aligns with the role of the G₂ checkpoint. The other options are incorrect: shortening mitosis (not related to G₂ function), stopping cell division permanently (not the role of G₂), and doubling chromosome number (not relevant as DNA is replicated, not chromosome number doubled in this context).

Answer:

It helps ensure new cells have complete, error - free DNA, supporting healthy growth.
