Question

Classify the Rabies virus (a rhabdovirus family member) and HIV-1 with both the Baltimore and genomic structure systems. Compare your results. What conclusions can be made about these two different methods?

a) Both Rabies virus and HIV-1 belong to Group II in the Baltimore classification and have a single-stranded DNA genome.
b) Rabies virus falls under Group V in the Baltimore classification with a single-stranded RNA genome, while HIV-1 belongs to Group VI with a single-stranded RNA genome.
c) Rabies virus is categorized under Group III in the Baltimore classification with a double-stranded DNA genome, whereas HIV-1 is in Group VII with a double-stranded RNA genome.
d) Rabies virus and HIV-1 are both placed in Group VI of the Baltimore classification with a single-stranded RNA genome.

Answer 1

The Baltimore classification system categorizes viruses based on their genomes and mode of replication. Rabies virus is classified as a Group V virus with a single-stranded RNA genome, while HIV-1 belongs to Group VI with a single-stranded RNA genome. The Baltimore classification system is independent of the genomic structure system and provides a complementary approach to virus classification.

Step-by-step explanation:

The Baltimore classification system categorizes viruses based on their genomes and mode of replication. Rabies virus is classified as a Group V virus with a single-stranded RNA genome, while HIV-1 belongs to Group VI with a single-stranded RNA genome. Therefore, option b is correct.

The Baltimore classification system is independent of the genomic structure system. It focuses on the replication mechanism and mRNA production, while the genomic structure system classifies viruses based on their genetic material. The two methods complement each other in providing a comprehensive understanding of virus classification.
