How does a gel electrophoresis work
WebOne application of gel electrophoresis in DNA analysis is that it can reveal an individual’s genotype at a specific genetic locus. In this case, the DNA segments loaded into a sample well are copies of the DNA from one chromosomal region or locus from a single individual. In most applications, the DNA segment copies are made with the use of ... Weba) Gel electrophoresis uses an electric field to move charged molecules through a gel matrix. In the case of DNA or RNA, the negatively charged phosphate groups of the …
