Cell Cycle

Question 1

What’s the cell cycle?

Answer 1

As cells grow and divide, they cycle through
specific events in a regular pattern; this is
referred to as the cell cycle.

Question 2

Interphase

Answer 2

The cell grows and replicates its DNA and centrioles.

Question 3

G1 phase

Answer 3

It is the first part of the interphase period, where cells do most of the growing. They increase in size, and synthesize new proteins and organelles.

Question 4

S phase

Answer 4

(synthesis) involves some growth,
and the replication of the DNA molecule. Single-stranded chromosomes duplicate and become double-stranded.

Question 5

G2 phase

Answer 5

Shortest phase in the cycle. It manufactures many organelles and molecules needed for cell division.

Question 6

M phase

Answer 6

The (cell division) phase of the cell cycle occurs after the G2 phase. It occurs quickly and involves mitosis and cytokinesis.
