CELL CYCLE

Question 1

what is cell cycle

Answer 1

it is the regulated sequence of events that occur between on cell division and the next

Question 2

what are the three phases in the cell cycle

Answer 2

interphase
mitosis
cytokinesis

Question 3

what is the movement from one cell phase to the next triggered by

Answer 3

cyclins

Question 4

what happens during interphase

Answer 4

the cell increases in size and mass and carries out its normal functions such as synthesizing proteins and replicating DNA

Question 5

what are the three phases in interphase

Answer 5

G1 phase
S phase
G2 phase

Question 6

what occurs during G1 phase

Answer 6

a signal is received which tells the cells to divide. cells make the

Question 7

what happens during S phase

Answer 7

the DNA in the nucleus replicates which makes each chromosome forming two sister chromatids

Question 8

what happens during G2 phase

Answer 8

the DNA is synthesized is checked and the cell continues to grow and errors that are made are repaired

Question 9

what happens mitosis (M phase)

Answer 9

cell growth stops

Question 10

what happens during cytokinesis

Answer 10

once the nucleus has divided into two genetically nuclei the cell divides and one nucleus moves into each cell to create two genetically identical daughter cells. in plant cells a new cell wall is formed and in animal cells there is constriction of the cytoplasm between the two new nuclei
