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. WebHIV-1 provirus containing sense orientation RNase L cDNA caused increased expression of RNase L and 500- to 1,000-fold inhibition of virus replication in Jurkat cells for a period of about 2 weeks. Subsequently, a partial deletion of the RNase L cDNA which coincided with increases in virus production occurred.
