Identify the stages of the cell cycle using the drop-down menus. Label A-E
Ostrovityanka [42]

Picture attached

Answer:

A - G1 phase

B - G2 phase

C - S phase

D - Mitosis

E - Interphase

Explanation:

Interphase is all the parts of the cell cycle excluding mitosis, and encompasses G1, S, and G2 phases. Cells spend most of their lives in interphase

G1 is the first gap phase, where the cell is growing and making checks in preparation for mitosis. During S phase (the synthesis phase), the DNA is replicated. This is so a full copy of the DNA can be passed on to the daughter cells.

During the G2 phase, the final checks are made before the cell undergoes mitosis, which is where the cell divides.
