Question

The transcription of an integrated retroviral DNA in the genome functions to supply what products for the replication virus?

A. more RNA genome copies

B. RNA for translation into protein for the viral coat/envelope

C. more copies of the genome and protein for the viral coat/envelope

D. RNA intermediates for direct integration into another location in the genome

Answer 1

The transcription of integrated retroviral DNA in the genome supplies more copies of the genome and protein for the viral coat/envelope. Retroviruses have an RNA genome that is reverse transcribed into DNA and then integrated into the host's DNA. The integrated viral DNA produces transcripts that are translated into proteins for viral particle formation.

Step-by-step explanation:

The transcription of an integrated retroviral DNA in the genome functions to supply more copies of the genome and protein for the viral coat/envelope. Retroviruses, such as HIV, have an RNA genome that must be reverse transcribed to make DNA, which then is inserted into the host's DNA. The integrated viral DNA produces transcripts that are translated into proteins necessary to form an infectious viral particle.
