STR Analysis Biology Enriched

DNA Profiling/ DNA Fingerprinting Use of DNA to determine paternity or culprit of a crime Extract DNA, cut it into smaller fragments (restriction enzymes) Run a gel electrophoresis of it! Look for matches! https://www.youtube.com/watch?v=AkBUriMK9u8

Short Tandem Repeats (STRs) 1. Repeat DNA unique to each person 2. You inherit your STRs from each parent 3. Used in DNA fingerprinting https://www.youtube.com/watch?v=9bEAJYnVVBA https://www.youtube.com/watch?v=DbR9xMXuK7c
