Question

Of the following, which sequence is present in Rous Sarcoma Virus?

• A. DNA - RNA - proteins
• B. DNA - DNA - proteins
• C. RNA - DNA - proteins
• D. RNA - DNA - RNA - proteins

Answer 1

The correct option is D RNA - DNA - RNA - proteins

Rous Sarcoma Virus (RSV) is a retrovirus. It has RNA as a genetic material. It contains reverse transcriptase enzyme which uses RNA as a template and DNA is transcribed into DNA. This DNA is then transcribed into RNA in the host cell. This mRNA is then translated using host cell machinery into protein products.

Thus, the correct answer is option D.
