sentences:  In order to achieve this task, eukaryotic cells have proteins in place during certain points in the replication process that are able to detect any errors during DNA replication and are able to preserve genomic integrity.These checkpoint proteins are able to stop the cell cycle from entering mitosis in order to allow time for DNA repair.Checkpoint proteins are also involved in some DNA repair pathways, while they stabilize the structure of the replication fork to prevent further damage.
