As humans, we share most of our DNA with each other, but how do we determine the differences between our individual DNA sequences? Restriction enzymes are proteins that recognize specific DNA sequences and can be used to determine whether a particular DNA sequence is present. Join DNALC instructor Allison as she introduces restriction enzymes and gel electrophoresis. She will also walk you through an example of how DNA collected from a crime scene could be used to identify the person who left their DNA at the scene!
In this DNALC Live session, you will:
• Learn about restriction enzymes
• Watch a time-lapse video of DNA fragments being separated through a gel
• Determine who left their DNA at a “crime scene”
