Splet17. avg. 2024 · Polymerase chain reaction (PCR) is a technique used to "amplify" small segments of DNA. What is PCR? Sometimes called "molecular photocopying," the polymerase chain reaction (PCR) is a fast and inexpensive technique used to "amplify" - copy - small segments of DNA. SpletThe polymerase chain reaction ( PCR) is a method widely used to rapidly make millions to billions of copies (complete or partial) of a specific DNA sample, allowing scientists to take a very small sample of DNA and amplify it (or a part of …

SpletPCR is a relatively simple approach for enriching template DNA for sequencing. High-fidelity PCR is highly recommended for preparation of sequencing templates, in order to maintain DNA sequence accuracy.
