It can also be used to prevent deaths and detect harmful drugs in someone. Beacause of the advancements in forensic pathology it has become one of the most helpful contributions to humankind.

He can tell if it was a set up suicide or really a homicide by studying injuries that could have resulted from gunshots, poisoning, or a forceful blow. All this info is very expensive to generate though.

Without polymerase chain reaction procedures, capillary gel electrophoresis, or the ABI sequence analyzer DNA tests couldn't even take place. All these tests is how information is found. It used to take 2 to 4 weeks, but now it only takes 2 to 3 days. It all begins when police give specimens to the laboratory where pathologists discover evidence as they run the tests. The technologists search DNA for genetic markers by amplification and run the amplification on a sequence analyzer.
