Quizplus · Accepted Answer

The central dogma states that genetic information flows from DNA to RNA to protein, but in the case of retroviruses, their RNA genome is reverse transcribed into DNA by an enzyme called reverse transcriptase, so it goes against the flow of genetic information described by the central dogma. The other answer choices are not correct, as a virus is considered to be an organism by some definitions, viruses do have genetic material (either DNA or RNA), retroviruses do not lack DNA (as they produce it through reverse transcription), and the viral mutation rate is not relevant to this question.
