The touchdown polymerase chain reaction or touchdown style polymerase chain reaction is a method of polymerase chain reaction by which primers avoid amplifying nonspecific sequences. The annealing temperature during a polymerase chain reaction determines the specificity of primer annealing.
Reaksi berantai polimerase (bahasa Inggris: polymerase chain reaction, disingkat PCR) adalah metode untuk menciptakan jutaan hingga miliaran salinan dari segmen asam deoksiribonukleat (DNA) tertentu, yang memungkinkan ilmuwan untuk melipatgandakan sampel DNA yang sangat sedikit hingga mencapai jumlah yang cukup untuk dipelajari secara detail.

What is polymerase chain reaction (PCR)?
The polymerase chain reaction ( PCR) is a method widely used to make millions to billions of copies of a specific DNA sample rapidly, allowing scientists to amplify a very small sample of DNA (or a part of it) sufficiently to enable detailed study. PCR was invented in 1983 by American biochemist Kary Mullis at Cetus Corporation.
Reaksi berantai polimerase tersarang ( bahasa Inggris: Nested PCR) adalah suatu teknik perbanyakan ( replikasi) sampel DNA menggunakan bantuan enzim DNA polimerase yang menggunakan dua pasang primer PCR untuk mengamplifikasi fragmen. [1] .
May 1, 2018 · Abstract. "Touchdown polymerase chain reaction (PCR)" is a method to decrease off-target priming and hence to increase the specificity of PCRs. In touchdown PCR the temperature selected for the annealing step is initially set 5°C-10°C higher than the calculated Tm of the primers. Annealing under conditions of high stringency favors the ...

Hot start PCR is a modified form of conventional polymerase chain reaction (PCR) that reduces the presence of undesired products and primer dimers due to non-specific DNA amplification at room (or colder) temperatures.
