Question

1. What

events take place during the cell cycle?


2. How does the structure of DNA
help account for the way in which DNA copies itself?

Answer 1

What happens during each stage of the cell cycle?

The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
