Why is the eventual generation of viral mRNA necessary for viral replication

Viral mRNA codes for viral DNA necessary for viral progeny

Viral mRNA prevents the host cell immune response from destroying viral nucleic acid and proteins

Viral mRNA binds to a receptor in the interior of the cell membrane, allowing cell lysis and the escape of viral progeny

Viral mRNA codes for proteins, which every virus is fundamentally composed of in addition to nucleic acid

All of the above

Homework Answers

Answer #1

Option D is correct.

Explanation:

Retroviruses contain RNA genomes.

They contain a special enzyme known as Reverse Transcriptase which converts RNA to DNA.

Once the virion enters a host cell, it releases its RNA genome which is reverse transcribed into DNA.

This DNA serves as a template new RNA molecules which can be packed into new virions.

It also serves as the template for transcription of viral genes which are required for its life cycle (lytic or lysogenic).
