  1. RFLP • “Restriction Fragment Length Polymorphism” • Basic idea: • If two DNA sequences have different numbers or locations of restriction sites, they will differ in their restriction enzyme digest pattern • Uses: • Paternity testing • Criminal cases • Locating disease genes

  2. Criminal Case http://www.scientific.org/case-in-point/articles/thompson/

  3. Paternity testing Child 2 Child 1 Dad Mom

  4. Recombinant DNA • Engineered pieces of DNA inserted into the genomes of a target organisms • Can be used to mass produce useful proteins • “Humulin” – human insulin produced by bacteria (Eli Lilly company) • Human growth hormone • Also used to modify organisms • All originally depends on restriction enzymes!
