B Restriction enzymesare called molecular scissors or chemical scalpels. Although these enzymes are subtly different they both have two capabilities that make them suitable for PCR. Was found in cultured mouse embryonic stem ES.

CDNA is the result of reverse transcription by enzymes called reverse transcriptases. Was found as part of a natural mechanism used by plants to protect themselves from viruses. Which of the following is an application that uses PCR.

DNA Polymerase synthesises new strands of DNA complementary to the template DNA. So the correct answer is Taq polymerase. The DNA polymerase can add a nucleotide to the pre-existing 3-OH group only.

C Taq DNA polymerase D HRP View Answer Explanation. The DNA polymerase typically used in PCR is called Taq polymerase after the heat-tolerant bacterium from which it was isolated Thermus aquaticus. It is the process in which multiple copies of the gene or segment of DNA of interest are synthesised in vitro using primers and DNA polymerase.

Biotech Engineering MCQs Sub Category. Home Data Structure Singly. To amplify a segment of DNA using PCR the sample is first heated so the DNA denatures or separates into two pieces of single-stranded DNA.

None of the DNA polymerases that have been characterized thus far can direct de novo synthesis of a polynucleotidic molecule from individual nucleotides.
