WebReverse transcription is a technique used by researchers to generate a complementary strand of DNA (cDNA) from RNA. The technology is based on a retroviral mechanism whereby the enzyme reverse transcriptase can reverse transcribe RNA into DNA. This is especially helpful when scientists only have tissue and want to study gene sequence. WebReverse transcription reactions involve three main steps: primer annealing, DNA polymerization, and enzyme deactivation ( Figure 6 ). The temperature and duration of these steps vary by primer choice, target RNA, and reverse transcriptase used. Figure 6. Three main steps of cDNA synthesis.
