Module 2 - Cell Division (interphase) Flashcards
1
Q
what is interphase a process of?
A
growth
protein synthesis
replication
2
Q
what happens during interphase?
A
multiple checkpoints
- check for errors in replication
- repair enzymes
- self-destruction (apoptosis)
3
Q
what are the steps in interphase?
A
G1
G0
S
G2
4
Q
summarise G1:
A
- first growth phase
- protein synthesis
- organelle synthesis
CHECKPOINT
- cell size
- growth
- damage
- nutrients
5
Q
summarise G0:
A
- resting
- if cell hasnt reached G1 criteria
- due to damage/limits
6
Q
summarise S:
A
- DNA synthesis
- chromasomes are checked to ensure correct repliction
- if rep not successful cycle is stopped
7
Q
summarise G2:
A
- rapid cell growth
- molecules for cell division synthesised
- cycle delayed for any repair
CHECKPOINT
- cell size
- damage
- replication
- chromosomes attatched properly
