How is pcr used in forensics
WebDeveloped in 1991, DQ alpha testing was the first forensic DNA technique that utilized the polymerase chain reaction. This technique allowed for the use of far fewer cells than RFLP analysis making it more useful for crime scenes that did not have the large amounts of DNA material that was previously required. The DQ alpha 1 locus (or location) was also … Web1 jun. 2024 · Capillary Electrophoresis: Capillary electrophoresis is used to separate ionic species based on their size: charge.
