The mitotic cell cycle encompasses four sequential ordered phases that temporally distinguish the replication of genetic material from the segregation of duplicated chromosomes into two daughter cells. Lag or gap (G) phases therefore separate the replication of the DNA (S phase) and the segregation ...
