Chapter 17, Problem 8P

A.

Summary Introduction

To explain: Which cells are in G1, S, G2, and M phases of the cell cycle.

Introduction: The DNA in each chromosome must first be faithfully replicated to produce two complete copies. The cell division cycle or cell cycle comprises of different phases. Two basic phase include the interphase and mitotic phase (M phase). Interphase has three subparts: G1, S, and G2. Mitotic phase is divided into prophase, prometaphse, metaphase, anaphase and telophase. An inhibitor can be used to halt the cell cycle at specific phase and use of a dye like Hoechst 33342 which bind with the DNA that can be monitored by flow cytometer.

Summary Introduction

To draw: The distribution of cells that were treated with the inhibitors that block the cell cycle in the G1, S, or M phase.
