Question: why is taq polymerase preferred in pcr?
Answer: Taq Polymerase is Preferred Enzyme for Polymerase Chain Reaction (PCR) ... As the polymerase binds to DNA, it adds nucleotide in the direction of 5' to 3'. Unfortunately, because it disables at a higher temperature, DNA Polymerase is not suitable for a type of replication called Polymerase Chain Reaction (PCR).
