Reverse transcription polymerase chain reaction (RT-PCR) is a laboratory technique combining reverse transcription of RNA into DNA (in this context called complementary DNA or cDNA) and amplification of specific DNA targets using polymerase chain reaction (PCR). It is primarily used to measure the amount of a specific RNA. This is achieved by monitoring the amplification reaction using fl… WebFeb 28, 2024 · It involves DNA primers, DNA bases, enzymes, a buffer solution, and thermal cycling to help replicate these sequences.
