When cell has stalled DNA replication fork, which checkpoint should be predominantly activated? (a) G 1 /S (b) G 2 /M (c) M (d) Both G 2 /M and M
Option B If cell has stalled DNA replication fork, it implies that it has crossed CG 1 or G 1 cyclin cell cycle check point and has entered Sphase of cell cycle, where it is preparing for chromosome replication. Afterwards it will enter G 2 phase and will soon approach second check point called mitotic cyclin (CM) which lies between G 2 and Mphase).
