PCR can be employed to investigate locus-specific methylation. The ideal reverse transcriptase is robust (highly active under a variety of conditions) and converts all primed RNA within a sample to cDNA, regardless of its abundance, length or secondary structure. Because inverse PCR facilitates the identification of an unknown region of DNA while the conventional PCR can only be used for amplification and identification of known DNA regions or known mutations. Although it is one of the most commonly used lab methods, many researchers still worry about the complexity of designing PCR experiments. Als Inverse Polymerase-Kettenreaktion oder kurz Inverse PCR versteht man eine Abwandlung der PCR, mit der man unbekannte Genbereiche amplifizieren kann. In the PCR dialog, review the primer names and phosphorylation state. Inverse PCR, like mixed-linker PCR, can be applied to picogram quantities of DNA isolated by methods that result in shearing. }); Man erhält somit mit ein wenig Glück einen bisher unbekannten DNA-Bereich der zwischen zwei zueinanderhin gerichteten Primern liegt und der eine für eine PCR passende Länge hat. The shape of DNA is a double helical structure which consists of nucleotides that wind around each other in a helical shape6. Diesen kann man dann mit der herkömmlichen PCR amplifizieren.
