13 DNA Fingerprinting RFLPs
4/29/2019 DNA Fingerprinting RFLPs Restriction fragment length polymorphisms When restriction enzymes are used to cut DNA they leave it in different size lengths The pattern left by the RFLPs after a Southern Blot technique is a DNA Fingerprint Used commonly in criminal cases and forensics

14 Southern Blot technique
4/29/2019 Southern Blot technique DNA of interest is cut by restriction enzymes Fragments are separated by gel electrophoresis Separates DNA by size Smaller fragments move farther than large fragments DNA is negatively charged, the ends of the gel are positively charged DNA bands are transferred (blotted) onto filter paper Radioactive tracers for visible bands
