| Enzyme that is used in PCR technology is |
| a) | Taq polymerase | b) | Polymerase |
| c) | Helicase | d) | Reverse transcriptase |
| (a)The polymerase chain reaction (PCR) is a technique by which small samples of DNA can be quickly amplified. The repeated amplification is achieved by the use of thermostable DNA polymerase, i.e., (Taq-polymerase isolated from a bacterium, Thermus aquaticus) which remain active during the high temperature induced denaturation of double-stranded DNA. |
