RT-PCR (Reverse Transcription Polymerase Chain Reaction) ⎼ Molecular Biology Context
RT-PCR, or Reverse Transcription Polymerase Chain Reaction, is a widely utilized molecular biology technique employed for quantifying RNA expression levels. This process fundamentally involves converting RNA into complementary DNA (cDNA) through a process called reverse transcription. Subsequently, the cDNA undergoes Polymerase Chain Reaction (PCR) amplification.
The initial step in RT-PCR is reverse transcription, where RNA is transformed into single-stranded cDNA. This conversion is crucial as PCR requires a DNA template. Following reverse transcription, PCR amplifies the cDNA, allowing for the detection and quantification of the original RNA amount. The technique’s sensitivity makes it invaluable for studying gene expression.
RT-PCR’s applications span numerous biological research areas, including gene expression analysis, viral load determination, and diagnostic testing.
