WebFive core ‘ingredients’ are required to set up a PCR. We will explain exactly what each of these do as we go along. These are: the DNA template to be copied primers, short stretches of DNA that initiate the PCR reaction, designed to bind to either side of the section of DNA you want to copy DNA nucleotide bases? (also known as dNTPs). WebStart and end with 1-2 G/C pairs. Melting temperature (Tm) of 50-60°C. Primer pairs should have a Tm within 5°C of each other. Primer pairs should not have complementary regions.
