Forensic Science True Crime Investigation: DNA Profiling
Have you ever wondered how scientists work with tiny molecules that they can't see? Here's your chance to try it yourself! Sort and measure DNA strands by running your own gel electrophoresis experiment.
The Innocence Project is a non-profit legal clinic affiliated with the Benjamin N. Cardozo School of Law at Yeshiva University and created by Barry C. Scheck and Peter J. Neufeld in 1992. The project is a national litigation and public policy organization dedicated to exonerating wrongfully convicted people through DNA testing and reforming the criminal justice system to prevent future injustice.
Modern crime detection benefits greatly from the analysis of DNA taken from crime scenes. This analysis is called "DNA fingerprinting" and it's an extremely useful method of identification since it is so accurate. (It's impossible for two people to have exactly the same DNA unless they're identical twins!). On the other hand, collecting DNA evidence raises other questions:
How ethical is it to keep a database of convicted felons' DNA profiles? Can we rely on DNA fingerprints for conviction? Many ethical issues surround the use of DNA in forensic technology.
DNA Profiling and DNA Fingerprinting
Paul Andersen describes the process of DNA fingerprinting and DNA profiling. He explains how variability in STRs can be used to identify individuals. He explains the importance of DNA fingerprinting in forensics and paternity cases.
