Why Is Taq DNA Polymerase Used In PCR Reactions Rather Than A Normal DNA Polymerase?

Why Is Taq DNA Polymerase Used In PCR Reactions Rather Than A Normal DNA Polymerase? Why is Taq DNA polymerase used in PCR reactions rather than a ‘normal’ DNA polymerase? Taq polymerase is stable at the high temperatures that are used in the PCR reaction. If you start with one double-stranded DNA molecule and you
