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. WebComplementary DNA (cDNA) is synthesized in the laboratory from messenger RNA (Fig. 18-3 ). cDNA is not genomic DNA, because the transcript of genomic RNA has been processed (i.e., it lacks promoters and introns). The enzyme reverse transcriptase (see Chapter 15) is used to synthesize double-stranded DNA that is a complementary copy of the mRNA.
