Function of dna template in pcr

WebThe PCR reaction requires a DNA template, two primers that flank the target sequence, a thermostable DNA polymerase, deoxynucleotide triphosphates (dNTPs), and a buffer solution. The PCR reaction is carried out in a thermal cycler, which can rapidly heat and cool the reaction mixture to different temperatures for different steps in the reaction. WebJul 27, 2024 · Even though in theory, one molecule of the template would be sufficient, considerably larger amounts of DNA are typically used for a classic PCR, for example, up to 1 µg of genomic mammalian DNA and as little as 1 pg of plasmid DNA (1). The optimal amount depends largely on the number of copies of the target sequence, as well as on …
