Functions of Taq DNA Polymerase in PCR Reaction

DNA digest at 37 degree Celsius like body temperature because body temperature is optimal for most other enzymes, If the temperature too hot enzymes may be denatured and killed, if the temperature too cool enzyme activity become lower and required longer time for digestion, Each enzyme digest or cut DNA at specific sequence called restriction site and each recognition site have 4 or 6 base pair called palindromic sequences #geneticteacher
