Cell cycle

Question 1

cell cycle

Answer 1

series of event that take place from one cell division to the next.

It includes: interphase (G1,S,G2) and the mitotic phase (mitosis and cytokinesis)

Question 2

G1

Answer 2

The cell produces new proteins, grows and carries out its normal tasks for the body.

This phase ends when the cells DNA begins to replicate.

Question 3

S

Answer 3

The DNA molecules in the nucleus form exact copies of themselves

Question 4

G2

Answer 4

Involves preparation for cell division

Question 5

M

Answer 5

cells divide into two daughter cells.

Question 6

G0

Answer 6

After the cell division, cells may continue the cell cycle and re-enter the G1 phase.

Some cells leave the cycle and stop dividing for days, years or a lifetime. These cells are in the G0 phase

Question 7

Interphase

Answer 7

Is the period between the nuclear divisions.

During interphase, the cell goes through G1, S, G2 phases of the cell cycle.

In the S phase, the DNA molecules in the nucleus form exact copies of themselves.

Thus, in the period between one cell division and the next, the quantity of DNA in the nucleus doubles.
