Reverse Transcription |
Reverse transcription is the process of transcribing RNA molecules into complementary DNA. This cDNA synthesis reaction is mediated by enzymes called reverse transcriptases, or RTs. Moloney murine leukemia virus (M-MLV) reverse transcriptase is one of the RTs used in molecular biology workflows. However, novel engineered RTs are often preferred for enhanced efficiency, improved thermostability, and higher cDNA yields.
Learn how our commitment to enzyme excellence, including the exceptional reliability and performance of SuperScript Reverse Transcriptases, are leading the way in the pursuit of science.
How do reverse transcriptases work?
Reverse transcription reactions involve multiple steps to synthesize cDNA. Reverse transcriptases exhibit several distinct biochemical activities, predominantly RNA-dependent DNA polymerase activity and RNase H activity. Firstly, reverse transcriptase binds to an RNA template in the presence of an annealed primer. Next, the RNA-dependent DNA polymerase activity of the enzyme synthesizes cDNA by incorporating dNTPs from the reaction mix. This generates a cDNA:RNA hybrid and is referred to as first-strand cDNA synthesis. If reverse transcriptase exhibits RNase H activity (as in wild-type M-MLV RT), the RNA of the cDNA:RNA hybrid is cleaved during first-strand synthesis. In engineered enzymes, RNase H activity is often reduced to prevent premature RNA degradation.
