What is interphase?
when cell grows and prepares to divide, organelles replicated, cell enlargement.
Growth 1
cell enlargement
organelles replicate
cell growth
Synthesis
46 chromosomes are replicated.
DNA replication
Growth 2
final checks made before cell division.
DNA are checked for errors sure theres no mutations.
repairs are made using polymerase
Growth 0
Highly specialised cells no longer divide (arrested cell cycle)
senescent cells: conditions arent ideal for them to continue onto division.
How is the cell regulated?
Checkpoints:
regulatory proteins: ones that stop to ensure the cell isnt damaged.
ones that continue the cell cycle after checks.
