Q. Polymerase chain reaction is most useful in :
(a) DNA synthesis
(b) DNA amplification
(c) Protein synthesis
(d) Amino acid synthesis
Solution :
Correct option : B 1.The polymerase chain reaction is a biochemical technology. 2.It is used to amplify or multiply a single copy of DNA with excellent accuracy and speed. 3.Taq polymerase enzyme polymerizes the new DNA strand utilizing single-stranded DNA as a template and DNA oligonucleotides during this process. 4.DNA amplification, a form of nucleic acid amplification, is the intentional increase in the number of copies of a specific DNA fragment into millions of copies by replication of the segment into which it has been cloned. 5.The polymerase chain reaction (PCR) is a typical method for rapidly making millions to billions of copies (complete or partial) of a given DNA sample, allowing scientists to take a little amount of DNA and amplify it (or a portion of it) to a large enough quantity to analyse in-depth.
