Chapter 12, Problem 8TYU

Summary Introduction

To review:

Compare and contrast the effects of removing growth factors from asynchronous cultures of human cells that are normal and those that are cancerous.

Introduction:

A normal cell will undergo all the phases of the cell cycle, that is, two gap phases (G1 and G2), synthesis phase (S), and mitosis phase (M) in a controlled manner. While cancerous cells undergo the cell cycle in an uncontrolled manner. Growth factors are proteins required for the growth in the living cells. Asynchronous cultures or cell cultures contain cells that are all in the different growth stages.
