Document Summary
Check point at this phase to see if dna replication has occurred properly. Once replicated and divided, cells can further divide or can enter a resting phase (g0) where they can stay or be induced back into the cycle. Mitosis single set of cells, duplicated and divided into two diploid cells. Non-conservative change; to decrease number of mutation, opening of the double helix, and each strand will then be replicated one at a time. Circular dna, compared to linear found within eukaryotes. Because the dna is circular, polymers (catalyze new strands of dna) go in, and proceed from either side of the origin of replication, making two new sets. Considered a semi-conservative change, as the old dna is never lost. Multiple origins of replication in eukaryotic dna. Replication bubbles arise at points along the dna and synthesis proceeds along a fork in each direction from these points.
