Unit II Homework

Cancer and Genetics

Introduction

In order for organisms to grow, repair, maintain, and reproduce, cells undergo cell division. Sometimes, cells uncontrollably divide, resulting in cancer. In the first part of the Cancer and Cell Division Lab, you will learn about normal cell division and will compare it to cell division that occurs in cancer cells. You will then visit a website to find out more information about cancer. You will learn why it occurs, why it kills, and new treatments that are being tested and used to treat cancer.

Objectives

1. Explain the process of cancer, the effects on the human body, the various types, and the risk factors involved.

2. Explain various treatments for cancer.

3. Explain the various stages of mitosis.
