Cold Spring Harbor Monograph, Volume 31 Extensive text on the replication of DNA, specifically in eukaryotic cells, for researchers. 68 contributors, 54 U.S. WebEach genomic locus in a eukaryotic cell has a distinct average time of replication during S phase that depends on the spatial and temporal pattern of replication initiation events. Replication timing can affect genomic integrity because late replication is associated with an increased mutation rate.
