- A researcher, studying two different animal viruses (A and B) that infect the same cell type, digests away all the protein and transfers the nucleic acid directly into the host cell. Only virus B causes the infection. This suggests: a. Virus A is likely to be a naked virus. b. Virus A is likely to be an enveloped virus. c. Virus A is likely to be a -ssRNA virus. d. Virus A is likely to be a +ssRNA virus. e. Virus A is likely to be a dsDNA virus.
