prereplicative造句

• A licensing factor which is required for replication initiation binds to origins in the prereplicative state.
• Entry into S-phase during endoreplication ( and mitosis ) is regulated through the formation of a prereplicative complex ( pre-RC ) at replication origins, followed by recruitment and activation of the DNA replication machinery.
• Early experimental evidence on the regulation of DNA replication suggests that replication origins exist in one of two states during the cell cycle : a prereplicative state in G1 and a postreplicative state from the moment of initiation until passage through mitosis.
