Answer 1

Answer:

When cell has stalled DNA replication fork, which checkpoint should be predominantly activated ?

(1) G₁/S

(2) G₂/M ✔✔

(3) M

(4) Both G₂/M and M

Answer 2

Answer :

When the DNA replication in the S-phase is stalled, the DNA replication and synthesis is not complete. This causes the activation of the G2/M checkpoint which does not allow the cell to enter the G2 and the M phase till the replication is complete.

So, the correct answer is 'G2/M
