"WebA simple formula for calculation of the T m is. T m = 4 (G + C) + 2 (A + T)°C. Thus, the annealing temperature chosen for a PCR depends directly on length and composition of the primer (s). One should aim at using an annealing temperature (T a) about 5°C below the lowest T m of the pair of primers to be used. " - During which step of pcr do primers attach
