MCQ
Enzyme that is used in $PCR$ technology is
  • ✓
    Taq polymerase
  • B
    Polymerase
  • C
    Helicase
  • D
    Reverse transcriptase
✓

Answer

Correct option: A.
Taq polymerase
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 $DNA$.
