DNA Fingerprinting (protocol only)

DNA fingerprinting is a technique used in biotechnology laboratories to establish links between various samples of DNA. These samples would likely be taken from several different sources and compared to see if – or how well – they match. Scientists are able to determine relationships among the sources of DNA depending on the results of the “fingerprint” using gel electrophoresis.

In this activity, students will prepare several DNA samples and analyze them using gel electrophoresis.
