3. The Cell Cycle Interphase
Cell spends most of its life here (average mammalian cell, about 90% of life) G1
Cell double organelles
accumulates materials needed for DNA synthesis S
DNA replication occurs G2
Cell synthesizes the proteins needed for cell division
The Cell Cycle

4. Some cells—such as nerve and muscle cells—typically do not complete the cycle and are permanently in the G1 stage.
Embryonic cells spend very little time in G1 and complete the cell cycle in a few hours.
