Module 2 - Cell Division (interphase)

Question 1

what is interphase a process of?

Answer 1

growth
protein synthesis
replication

Question 2

what happens during interphase?

Answer 2

multiple checkpoints
- check for errors in replication
- repair enzymes
- self-destruction (apoptosis)

Question 3

what are the steps in interphase?

Answer 3

G1
G0
S
G2

Question 4

summarise G1:

Answer 4

• first growth phase
• protein synthesis
• organelle synthesis

CHECKPOINT
- cell size
- growth
- damage
- nutrients

Question 5

summarise G0:

Answer 5

• resting
• if cell hasnt reached G1 criteria
• due to damage/limits

Question 6

summarise S:

Answer 6

• DNA synthesis
• chromasomes are checked to ensure correct repliction
• if rep not successful cycle is stopped

Question 7

summarise G2:

Answer 7

• rapid cell growth
• molecules for cell division synthesised
• cycle delayed for any repair

CHECKPOINT
- cell size
- damage
- replication
- chromosomes attatched properly
