Circumstances in DNA-RNA template

Question

Is there any circumstances in that DNA is made based on the RNA template? Which enzyme is in it involved?

Answer 1

The procedure in that DNA is synthesized encompasses as template a RNA chain is named as reverse transcription. In cells infected which is by retroviruses (or RNA viruses, like AIDS or SARS viruses) reverse transcription happens and DNA is made from information contained in viral RNA. Viral RNA in host cell makes DNA with the aid of the enzyme called reverse transcriptase. Depends on that DNA the host cell then creates viral proteins, new viruses are collected and viral replication takes place.
