Chapter 9, Problem 11A

Summary Introduction

To determine:

The activities that take place in the interphase.

Introduction : 

The cell cycle is the complete cycle of the cells starting from the formation of the cells by mitosis and ends with the next mitosis. The cycle is divided into G1 phase, S phase, G2 phase and mitotic phase. 

Explanation of Solution

The interphase is the phase of cell cycle between two successive division. The G1 phase of the cell cycle is responsible for the growth and promotion of the cell size. The G2 phase occurs after S phase, so, there is no need of DNA replication. The S phase is the synthetic phase of the cell cycle. In this phase of the cell cycle the amount of DNA is doubled by the process of DNA replication.
