Question

Name the stage in the cell cycle where DNA replication occurs.

Answer 1

S phase (Synthesis Phase) is the phase of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase. Throughout the M phase and G1 phase, cells assemble inactive pre-replication complexes (pre-RC) on replication origins distributed throughout the genome. During S-phase, the cell converts pre-RCs into active replication forks to initiate DNA replication.
