The enzymes are encoded and used by viruses that use reverse transcription as a step in the process of replication. Reverse-transcribing RNA viruses, such as retroviruses, use the enzyme to reverse-transcribe their RNA genomes into DNA, which is then integrated into the host genome and replicated along with it. Reverse-transcribing DNA viruses, such as the hepadnaviruses, can allow RNA t… WebCorn in a tRNA scaffold was expressed off 5S, tRNA and U6 promoters. These promoters belong to three distinct subclasses of Pol III-dependent promoters. (b) Pol III transcription inhibition with actinomycin D reduces Corn fluorescence in mammalian cells. HEK293T cells were preincubated with 10 μM DFHO and then treated with 5 μg/ml actinomycin ...
