Question

nerve cells remain in which phase​

Answer 1

Answer:

Although AD-affected neurons can re-enter into the cell cycle, mitosis is rarely observed in these cells. Therefore, neurons that undergo S-phase block cell cycle progression at the G2/M transition, acquire a tetraploid condition, and survive for long time in the affected brain.

Answer 2

the cells enter S phase during which the DNA is replicated. ... Unlike most cell types however, neurons are generally considered incapable of proliferating once they are differentiated, as they are in the adult nervous system.
