What are the 2 main phases of the cell cycle

Interphase and Mitosis

15

What phase does the cell spend most of its time in?

Interphase

15

Why does a cell have to duplicate its DNA?

So the new daughter cells will have the same amount of DNA as the parent cell.

15

What is the first phase of Interphase and what is happening in the cell?

G1 - the cell is growing to maturity

15

When does DNA replicate in the cell cycle?

S-phase of Interphase

15
