Cell Cycle & Mitosis

Question 1

What is mitosis?

Answer 1

cell division to form 2 genetically identical daughter cells

Question 2

What does mitosis do?

Answer 2

growth + tissue repair

asexual reproduction

it has one division to form two daughter cells

Question 3

What is cytoknesis?

Answer 3

divison of the cytoplasm

most visible in telephase

Question 4

What are the stages of the cell cycle?

Answer 4

G1, S phase, G2, and mitosis

Question 5

What occurs at gap phase 1?

Answer 5

cell grows to normal size

organelles replicate

***checkpoint for g1
cell cycle is controlled by checkpoints - if conditions are OK - then continue to S-phase ELSE cell cycle stops and cell goes through apoptosis

Question 6

What happens at synthsis phase?

Answer 6

DNA is replicated for next cell division

Question 7

What happens at gap phase 2?

Answer 7

cell grows

cell division proteins made

**G2 checkpoint

cell checks DNA has been replicated properly

if OK - mitosis

if mutations or damage - stop cell cycle - repair DNA

Question 8

What are the four stages of mitosis?

Answer 8

prophase, metaphase, anaphase, and telophase

***metaphase checkpoint

• cell checks chromosomes have attached to the spindle

if OK - continue

if not - fix it - or apoptosis
