Which of the following enzymes is required in order to acquire templates for the process of quantitative PCR?

Question

Quizplus · Accepted Answer

Reverse transcriptase is required to convert RNA into complementary DNA (cDNA), which serves as a template for quantitative PCR when starting from RNA samples.  Reverse transcription-PCR (RTPCR) is a rapid and quantitative procedure for the analysis of the level of expression of genes. This technique utilizes the ability of reverse transcriptase (RT) to convert RNA into single-stranded cDNA and couples it with the PCR-mediated amplification of specific types of cDNAs present in the RT reaction. The cDNAs that are produced during the RT reaction represent a window into the pattern of genes that are being expressed at the time the RNA was extracted.
