Mature nerve cells, which are incapable of cell division, are most likely in
A) G1.
B) the S phase.
C) G2.
D) mitosis.
E) meiosis.

Question

Quizplus · Accepted Answer

Mature nerve cells are post-mitotic and have exited the cell cycle. They do not undergo cell division, so they are not in the S phase, G2, mitosis, or meiosis. They are in the G0 phase, which is a non-dividing state where cells are still metabolically active but do not prepare for division. Therefore, the best choice is A, G1, which is the stage of the cell cycle where cells prepare for DNA replication.
