Why is only one copy of DNA made per cell division cycle in eukaryotes despite the presence of multiple origins of replication?

#Unit 3. Fundamental Processes

  1. There is only one origin of replication per chromosome.

  2. The rate of elongation proceeds at a rate that allows only one copy to be made by the time the cell divides.

  3. The activity of an S-phase protein kinase controls the formation of the pre-replication complex.

  4. Primase is activated by phosphorylation only at the onset of S-phase by S-phase protein kinase.
