School Break Bio!: Forensic DNA Fingerprint

Pre-registration is required.

Appropriate for ages 13-16.

Human DNA is more alike than different, so how do we find the differences? Restriction enzymes are proteins that recognize specific DNA sequences and can be used to determine whether a particular DNA sequence is present. In this lab, DNA from “evidence” and “suspects” will be compared using restriction enzyme digest and agarose gel electrophoresis. DNA analysis will then be combined with crime scene data to draw conclusions about each suspect.
