Summary Introduction

To determine:

The potential effect of an abnormally high level of a growth hormone on the regulation of the cell cycle.

Introduction:

Multicellular organisms have tight regulation on cell division, thus the division of cell only takes place when needed. Inactivation or activation of cell cycle is mainly regulated by hormones (signaling molecules). Growth hormones promote muscular growth and skeletal growth. The cell cycle is set of stages that take place between the cell division and the time resulting in formation of daughter cells.
