Is a lab technique used to establish a link between biological evidence and suspect in a crime investigation. It's a simple method of isolating and identifying variable elements within the base pair sequence of DNA. Crime scene investigation as a whole though is a tedious process that involves documentation of the scene and the different conditions at the scene, and collection of physical evidence. Most of the people responsible for analyzing the physical evidence are forensics, who test some of the evidence to see if there's any left over DNA or any clue as to how the crime scene went down.
Plasmids/recombinant DNA/ transgenic organisms
Small, circular, double stranded DNA molecule that is distinct from a cells chromosome DNA. Recombinant DNA being DNA that has been formed artificially by combining constituents from different organisms. Usually used in health and nutrition/ pharmaceuticals. Transgenic organisms are basically the same as gmo's and basically carry the same functions as explained before.
