Final answer:
The coronavirus is the virus with a genome that can be directly translated into proteins, as it is a positive-strand RNA virus. Other viruses listed require conversion into mRNA or transcription before their genomes can be translated.
Step-by-step explanation:
The student has asked which virus has a genome that can be directly translated into proteins. Among the choices given, coronavirus is the correct answer because it is a positive-strand RNA virus. The viral RNA of a positive-strand RNA virus like coronavirus can be used directly by the host cell's ribosomes as mRNA, which means the viral RNA can be translated into viral proteins immediately after infection.
On the other hand, smallpox virus and adenovirus are DNA viruses, hence their DNA must be transcribed to mRNA before translation. Influenza virus type A and Ebola virus have negative-strand RNA genomes, so they must be converted to a positive-strand (complementary mRNA) before translation can occur.
