Replication origin

Replication origin

A unique dNA sequence of a replicon at which dNA replication is initiated and proceeds bidirectionally or unidirectionally. It contains the sites where the first separation of the complementary strands occurs, a primer rNA is synthesised, and the switch from primer rna to dNA synthesis takes place. (rieger et al., glossary of genetics: classical and molecular, 5th ed)

Protein synthesis during S phase

As far as I remember being told, only histone synthesis is active during replication. I was guessing the inactivation of all other protein synthesis ... some phosphorylation, or something to do with steric impedement at the origin of replication. Still, that doesn't explain the histone part...
