Taq strand displacement activity
Did you know?
WebMultiple displacement amplification (MDA) is a DNA amplification technique. This method can rapidly amplify minute amounts of DNA samples to a reasonable quantity for genomic analysis. The reaction starts by annealing random hexamer primers to the template: DNA synthesis is carried out by a high fidelity enzyme, preferentially Φ29 DNA polymerase. WebToehold mediated strand displacement (TMSD) is an enzyme-free molecular tool to exchange one strand of DNA or RNA (output) with another strand (input). It is based on …
