Objectives

· Describe the role of mitosis in asexual reproduction, including how this process may contribute to or limit genetic variation.

· Review the importance and role of mitosis of a cell within in an organism.

· Relate specific events to specific stages of the cell cycle. (ALD)

· Predict and explain what is happening at the different stages of mitosis.

· Explain how mitosis forms new cells and its role in maintaining chromosome number during asexual reproduction and cell and body growth.

· Predict the effects of mistakes made in the process of mitosis in a cell on an organism.

· Explain the importance of cyclins and proteins in the role of cell growth.

· Assess how uncontrolled cell growth may result from mutations that affect the proteins that regulate the cell cycle.

Investigate ways to prevent cancer growth within the body
