In a certain procedure,short DNA strands that are complementary to DNA sequences on either side of the gene or DNA sequence of interest are synthesized and used to initiate its amplification in vitro by a special (heat-stable)DNA polymerase.The procedure is known as:
A) Telomerase Chain Reaction
B) Polymerase Chain Reaction
C) Gene cloning
D) DNA fingerprinting
E) Restriction Fragment Length Polymorphism

Question

Quizplus · Accepted Answer

The described procedure is the Polymerase Chain Reaction (PCR), which uses short DNA strands called primers to amplify specific sequences of DNA in vitro. PCR is a widely used technique in molecular biology for applications such as gene expression analysis, genetic testing, and DNA sequencing. The other options listed are not directly related to the procedure described.
