- Part B - Viral Classification: The Baltimore Scheme The Baltimore classification scheme is based on the relationship between the virus' genome and its mRNA. For the following choices, indicate which viruses would fall into each classification: 1) require reverse transcriptase to copy the information in their own genome to DNA; 2) can replicate and be transcribed in the same manner as the cell's own genetic material; and 3) a replicative form of DNA must be produced and is used for both replication and transcription. Drag and drop choices to the bins they describe. double-stranded DNA viruses Requires reverse transcriptase double-stranded RNA viruses retroviruses double-stranded DNA viruses that have an RNA intermediate Functions similarly to cell's own genetic material plus-strand RNA viruses minus-strand RNA viruses Reset Help plus-strand DNA viruses Uses a replicative form of DNADNA from a newly discovered virus was purified, and UV light absorption was followed as the molecule was slowly heated. The absorbance increase at the melting temperature was only 10%. What does this result tell you about the structure of the viral DNA?You have recently isolated a virus associated with a human disease. The virus particles are spherical, ~100 nm in diameter, and possess an envelope. Would you expect to find glycoproteins in the viral envelope? yes Would knowing that the particles are spherical mean that they are built with icosahedral symmetry? [Select]
