What is interphase?

when cell grows and prepares to divide, organelles replicated, cell enlargement.

2
New cards

Growth 1

  • cell enlargement

  • organelles replicate

  • cell growth

3
New cards

Synthesis

  • 46 chromosomes are replicated.

  • DNA replication

4
New cards

Growth 2

  • final checks made before cell division.

  • DNA are checked for errors sure theres no mutations.

  • repairs are made using polymerase

5
New cards

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.
