"WebThus, it is important to understand the features of the genome that determine the dynamics of replication. Initiation of DNA replication in eukaryotic cells takes place in two temporally separated steps ( 8 – 10 ). From late M through G1 phase, prereplication complexes (pre-RCs) are assembled at multiple sites in the genome. " - Some dna segments are active during cell
