Running head : PCR AND RCLF VS . MITOCHONDRIAL deoxyribonucleic acid TECHNIQUEDifferentiating PCR and RCLF Techniques from mitochondrial desoxyribonucleic acid Technique[Your name][University][Professor][Subject]Differentiating PCR and RCLF Techniques from mitochondrial desoxyribonucleic acid TechniqueRestriction lop duration polymorphism (RFLP ) is a basic technique in analyzing genomic DNA which throw out be utilise in forensic investigations . It utilizes the restriction enzyme , called restriction endonuclease , which cuts the lengthy DNA chain into fragments round specific sites on the chain depending on the type of enzyme that is utilise in the process called restriction digest (U .S . segment of cogency Office of light 2008 . Agarose gel electrophoresis is then(prenominal) active to separate the components by le ngth and is then transferred to a membrane by means of Southern blot rule . A recording label DNA probe upon hybridization of the membrane then determines the length of the fragments . In transmittable analysis , RFLP is an important phenomenon since it distinctiates individuals upon detecting different fragment lengths (allele ) between individuals . This technique requires large amounts of DNA (ExploreDNA 2008PCR on the other hand is a method of DNA acquire even , wherein it uses DNA polymerase to amplify regions in DNA that it targets from a guidebook DNA or RNA molecule . lower-ranking amounts of pattern can be used in the analysis , which is exceedingly applicable in forensic analysis , where it is potential that only a trace amount of sample can be found as evidence The product to be obtained is of high purity in all the available PCR methods . compare experimental DNAs in association with other results from other PCR methods is then a useful tool in identi fying a somebody or organism . This is compo! sed of three basic steps : denaturation of the genetic strong , hybridization or annealing , and DNA synthesis using the enzyme mentioned . The product is composed of a forsake of the certain DNA which already turns out to be single-stranded because of denaturation , positive(p) a strand of the replica (Powledge , ___ ,.

2There are limitations in the RFLP method that can be addressed by the method called Mitochondrial DNA (mtDNA ) analysis . In this method , DNA is obtained from a cellular organelle called the mitochondrion , compared to the PCR and RFLP where the sample needs to have turn cellular material t o be extracted . mtDNA is very valuable in solving cases that remained unsolved for so many years , with samples such(prenominal) as hair , bones and teeth , which cannot be canvass through PCR and RFLP since they do not contain nucleated cellular material . An application would be identification of a missing somebody through comparison of its mtDNA with the mtDNA of its potential maternal comparative (U .S . department of Energy Office of Science , 2008ReferencesExploreDNA (2008 .
