Cell Cycle Control
Interphase and Mitosis

2. Interphase G0- cells inactive, at rest, not preparing to divide
sometimes grouped in with G1

3. Interphase G1- Cell grows in preparation for DNA replication
reviews internal and external environment to ensure DNA replication can occur
synthesize proteins and mRNA, replicate organelles
can revert back to G0 if not ready

4. Interphase S phase- DNA is replicated! cell growth continues
proteins and enzymes for replication are synthesized

5. Interphase G2-intermediate phase
cell ensures it is ready to split into two cells
final chance to grow

6. Mitosis
Prophase
chromatin condenses
nucleolus disappears

7. Mitosis
Metaphase
chromosomes line up along the metaphase plate

8. Mitosis Anaphase chromosomes break at centromeres
sister chromatids move to opposite ends of cell

9. Mitosis Telophase and cytokinesis nuclear membrane reforms
chromosomes unwind
cell cleaves into two
