S
synthesis, cell replicates dna at end of the phase has two complete sets of chromosomes
Mitosis
cell division occurs
G0
cells enter if they are not needed because there is enough resources or if the organism is developed and not dividing like muscle cells and. Nerves and those cannot leave or liver cells
Stimulators cd,
Cdk cyclins adc/c
Inhibitors
Rb atm and p53, stops cells cycle causes cancer when both are stopped
Protooncogenes
Code for stimulation protein and become oncogenes when mutated is on for cancer
Tumor suppressor
code for inhibitory proteins if both p53 are off then cancer occurs
