DNA Gel Electrophoresis Fingerprinting Virtual Lab
Everyone has unique fingerprints but what if there are no fingerprints left at a crime scene to identify a suspect? How can officials identify guilty parties in a criminal case or identify unknown individuals?
Watch the following Nova video (6 minutes) for an introduction to answering the following question: How can DNA be used to identify one individual from another?
Can DNA Demand a Verdict?
Can DNA alone be used to convict someone of a crime and demand a verdict? Utah Genetics attempts to answer this question through the introduction of Gel Electrophoresis. Read this short article, http://learn.genetics.utah.edu/content/science/forensics/
Gel Electrophoresis Virtual Lab
Gel Electrophoresis is a process that allows for the separation of DNA, RNA, or protein fragments. Develop in the 1970s, this process is often used in forensic science to compare the DNA of different suspects in comparison to DNA evidence. The process is completed by adding samples (DNA, RNA, or proteins) to an agarose gel and applying electrical current to separate the molecules within the sample based on molecular weight. Gel Electrophoresis has become an extremely common tool in the laboratory in the analysis of DNA based samples. Utah Genetic’s virtual lab will provide an introduction to carry out this common technique.
