DNA Scavenger Hunt DNA Background Information
Each of you comes to this class with a wide range of knowledge concerning DNA. This scavenger hunt will give you the opportunity to show what you know and to discover that which you"forgot". You will be asked various questions and then given websities to help you find the answers. Use the worksheet provided in class. If you already know the correct answer and are confident about its accuracy, go to the next question.

Websites for help:

CASE STUDIES

There are several websites that give case studies showing the use of DNA evidence in the courtroom. Read those found on the Canadian DNA Data Bank. How does their history of DNA uses match with those of the U.S.?

Then look on the Crime Library for DNA Revolution. How will you be able to use this website during this unit?

 

CASE STUDY SCENARIO

THE TRIAL OF THE CENTURY--O.J. SIMPSON

A. Take notes over the video: Trial of the Century. In addition, you may wish to obtain extra background and evidence information from the internet, like the crime library.
