The answer is true.
Reverse transcriptase (RT), also called RNA-directed DNA polymerase, is an enzyme encoded by the genetic material of RNA viruses (retroviruses) that catalyzes the transcription of retrovirus RNA into DNA. RT is the main mechanism of retroviruses, which cause diseases in humans, including human immunodeficiency virus (HIV) and human T-cell lymphotropic virus I (HTLV-I), which causes leukaemia. Those viruses use the enzyme to transcribe their RNA genomes into DNA and then integrate it into the host genome.
