reverse transcription-polymerase chain reaction

Reverse transcription-polymerase chain reaction (RT-PCR) is a laboratory technique that uses an enzyme called reverse transcriptase to convert RNA into DNA. This synthesized DNA can then be amplified using the polymerase chain reaction (PCR) to create many copies of a specific DNA segment.12

This process is crucial because RNA is less stable and harder to study than DNA. By creating a complementary DNA (cDNA) strand from RNA, researchers can more easily analyze and amplify genetic material. RT-PCR is a powerful tool used in various fields, including molecular biology, medical diagnostics for diseases like cancer, and understanding genetics.21
