Retroviruses
To make DNA from mRNA
reverse transcriptase
This is reverse transcriptase. HIV drugs that block this part of the HIV lifecycle are called reverse transcriptase inhibitors.
RNA Polymerase - A polymerase that catalyzes the synthesis of a complementary strand of RNA from a DNA template, or, in some viruses, from an RNA template.
The enzyme, reverse transcriptase, uses an RNA template to create DNA. Then transcription is done normally to recreate an RNA template and then have it expressed as a polypeptide. By adding this extra step, the chance of mutations is greater so this process is important for quicker adaptations. For example, HIV uses reverse transcriptase and carries RNA instead of DNA.
Retroviruses are considered a special class of viruses because they transcribe RNA to DNA using reverse transcriptase. HIV uses reverse transcription to synthesize a DNA strand using its RNA genome as a template.
To make DNA from mRNA
Human Immunodeficiency Virus (HIV) is a retrovirus. A retrovirus is a RNA virus that replicates through a DNA intermediate. HIV synthesises DNA from RNA by the action of reverse transcriptase enzyme.
Reverse transcriptase use mRNA to form DNA. mRNA

This is reverse transcriptase. HIV drugs that block this part of the HIV lifecycle are called reverse transcriptase inhibitors.
Reverse transcriptase.
reverse transcriptase. With this enzyme, the RNA viruses can make DNA using their RNA as a template.
You might be referring to the reverse-transcription that many retroviruses use (a virus with an RNA that turns into DNA). By using the enzyme reverse transcriptase, viruses like HIV can make a DNA from RNA template.
Reverse transcriptase.
The reverse transcriptase enzyme is responsible for synthesis of DNA from an RNA template by the process of reverse transcription.
