WebbSample questions for one comprehensive exam for the EECB graduate program. WebbAs replication continues, the two origins move towards opposite ends of the cell, pulling the rest of the chromosome along with them. The cell also gets longer, adding to the separation of the newly forming chromosomes. Replication continues until the entire chromosome is copied and the replication enzymes meet at the far side.
