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

NEETNEET 2016Cell Cycle and Cell Division

Solution:

Stalled forks activate checkpoint signaling and pause replication. Since, G1/S checkpoint checks DNA damage, cells size prior to S-phase (i.e. DNA replication phase). This checkpoint would be activated by stalled DNA replication fork.
