Which of the following is not true of the Polymerase Chain R

Which of the following is not true of the Polymerase Chain Reaction?

PCR is facilitated by a heat labile DNA polymerase.

PCR can facilitate the detection of DNA that is too low to detect by other methods.

PCR is a method of replicating DNA in a test tube.

Solution

Option 1 is not true.

PCR is Facilitated by heat stable DNA polymerase enzyme not heat labile DNA polymerase enzyme. Enzyme used in PCR is TaqPolymerase. Isolated from thermal stable Thermus aquaticus bacteria.

By using PCR we can amplify little amount of DNA into million copies.
