Document Summary

Dna has to be replicated before going to daughter cells. The three cell cycle stages called g1, s, and g2 make up interphase, m is the short mitosis phase. During the s-phase of the cell cycle dna is replicated and histone and other protein synthesis is greatly increased. 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. Once the cell is replicated and divided it can either go on and back into g1 and repeat cycle and go into the g not phase (i. e liver cells) Dna is in double helix so it has to be opened up to be replicated (replicated in semi conservative form) The strands separate and each strand is replicated individually called semi conservative replication: this is because we want to make sure that the fewest amount possible mistakes are made.
