DNA Fingerprinting

http://www.pbs.org/wgbh/nova/sheppard/analyze.html

Objective: Students will learn the steps of DNA fingerprinting by creating a fingerprint in a virtual lab. They will use this fingerprint to solve a virtual crime. The virtual lab is interactive and goes through the step-by-step process of DNA fingerprinting

Create a DNA Fingerprint ( http://www.pbs.org/wgbh/nova/sheppard/analyze.html )
