cell cycle regulation

Question 1

cell cycle

Answer 1

life of a cell from its formation until it divides

Question 2

function for cell division

Answer 2

reproduction
growth
tissue repair

Question 3

phases of cell cycle

Answer 3

interphase (Gi phase, S phase, G2 phase)
miotic (M) phase (mitosis, cytokinesis)

Question 4

how much of the cell cycle in interphase

Answer 4

90%

Question 5

Gi phase

Answer 5

cell grows and carries out normal functions

Question 6

S phase

Answer 6

duplicates chromosones

Question 7

G2 phase

Answer 7

prepares for cell division

Question 8

how much of the cell cycle is the M phase

Answer 8

10%

Question 9

what happens during mitosis

Answer 9

nucleus divides

Question 10

what happens during cytokinesis

Answer 10

cytoplasm divides

Question 11

what alternation happens during the cell cycle

Answer 11

mitotic phase alternates with interphase
G1 🡪 S 🡪 G2 🡪 mitosis 🡪 cytokinesis

Question 12

checkpoint

Answer 12

control point where stop/go signals regulate the cell cycle

Question 13

major checkpoints in the cell cycle

Answer 13

Gi checkpoint (most important)
G2 checkpoint
M-spindle (metaphase) checkpoint
