Question

18-9 Which of the following descriptions is consistent with the behavior of a cell that lacks a protein required for a checkpoint mechanism that operates in G2?

Answer 1

If a cell lacks a protein required for a checkpoint mechanism that operates in G2, it would bypass the G2 checkpoint and potentially result in abnormal cell division and the formation of tumors.

Step-by-step explanation:

If a cell lacks a protein required for a checkpoint mechanism that operates in G2, it would likely result in the cell proceeding directly from G2 to M without proper checks and balances. This means that the cell would potentially enter mitosis even if there are issues with chromosome replication or DNA damage. Without the necessary protein, the cell would bypass the G2 checkpoint, leading to the possibility of abnormal cell division and potential consequences such as the formation of tumors.
