WebThe cell fusion experiments revealed three important phenomena. First, only chromosomes from G1 cells are competent to initiate DNA replication. Second, S-phase cells, but not cells in G1 or G2, contain an activator of initiation of DNA replication that can work on the competent (G1) chromosomal state.
