A retrovirus implies that:
The genetic information is transmitted as RNA
A surface antigen is required for infiltration to occur

Result in cell destruction
The Correct Answer is C
A. Retroviruses do indeed have RNA as their genetic material, but the key characteristic that defines them is their ability to reverse transcribe RNA into DNA.
B. While surface antigens play a role in viral entry, this does not specifically define a retrovirus.
C. Retroviruses, such as HIV, integrate their RNA into the host cell's DNA, which is a defining feature of this virus type and crucial for its replication cycle.
D. While retroviruses can lead to cell destruction over time, this is not a defining characteristic; many viruses can cause cell damage.
