Given Baltimore's scheme, a positive sense single-stranded RNA virus such as the polio virus would be most closely related to wh
ich of the following? A) T-series bacteriophages B) retroviruses that require a DNA intermediate C) single-stranded DNA viruses such as herpesviruses D) nonenveloped double-stranded RNA viruses E) linear double-stranded DNA viruses such as adenovirus
Given the baltimore's scheme which used for virus classifications, the most closely related option of virus to the described polio virus with a single stranded RNA in the question would be retroviruses that require a DNA intermediate.
Because much like the single-stranded RNA viruses, the retroviruses do not contain any DNA but they do have an enzyme named reverse transcriptase which they can use to replicate their RNA into the host cells DNA and use the end product for their benefits. So they both work in similar ways.
The common example of sublimation is shrinking of ice cubes that are not used in the freezer and conversion of dry ice rapidly into wispy clouds which vanish very soon
