Question

Expand PCR. Mention its importance in biotechnology.

Answer 1

Polymerase chain reaction (PCR) is a technique used to make numerous copies of a specific segment of DNA quickly and accurately. The polymerase chain reaction enables investigators to obtain large quantities of DNA that are required for various experiments and procedures in molecular biology, forensic analysis, evolutionary biology, and medical diagnostics.

The polymerase chain reaction is often considered as one of the most important scientific advances in the field of molecular biology. With this revolutionary yet inexpensive biochemical technology, it's possible to generate millions of DNA copies from a single strand of DNA.
