Running head : PCR AND RCLF VS . MITOCHONDRIAL deoxyribonucleic unpleasant TECHNIQUEDifferentiating PCR and RCLF Techniques from mitochondrial deoxyribonucleic acid Technique[Your name][University][Professor][Subject]Differentiating PCR and RCLF Techniques from mitochondrial desoxyribonucleic acid TechniqueRestriction crock up aloofness polymorphism (RFLP ) is a basic technique in analyzing genomic DNA which base be utilise in rhetorical investigations . It utilizes the restraint enzyme , called restriction endonuclease , which cuts the long DNA scope into fragments aggress specific sites on the chain depending on the type of enzyme that is utilize in the process called restriction digest (U .S . segment of dexterity Office of science 2008 . Agarose jelly electrophoresis is then(prenominal) sedulous to separate the components by space and is then transferred to a membrane through and through Southern touch rule . A grade DNA probe upon hybridizing of the membrane then determines the length of the fragments . In transmittable analytic thinking , RFLP is an important phenomenon since it assortediates individuals upon detecting different fragment lengths (allele ) between individuals . This technique requires large amounts of DNA (ExploreDNA 2008PCR on the other hand is a mode of DNA acquiring even , wherein it uses DNA polymerase to overstate regions in DNA that it targets from a guidebook DNA or RNA molecule . comminuted amounts of pattern can be used in the psychoanalysis , which is exceedingly applicable in forensic analysis , where it is apparent that only a tinge amount of try out can be found as evidence The growth to be obtained is of high purity in all the available PCR regularitys . canvass experimental DNAs in joining with other results from other PCR methods is then a useful lance in identifying a soul or organism . This is placid of three basic stairs : denaturation of the genetic actual , hybrid or annealing , and DNA synthesis using the enzyme mentioned . The product is composed of a range of the certain DNA which already turns out to be single-stranded because of denaturation , positive(p) a strand of the copy (Powledge , ___ ,.

2There are limitations in the RFLP method that can be turn to 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 nucleate cellular material to 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 deal nucleated cellular material . An application would be recognition of a missing someone through comparison of its mtDNA with the mtDNA of its potence maternal comparative (U .S . part of Energy Office of lore , 2008ReferencesExploreDNA (2008 .
