Question

Quizplus · Accepted Answer

Negative-sense single-stranded RNA viruses have only a few genes, including one that allows them to make mRNA from their genome.

Answer: B 
 This statement is false. Positive-sense single-stranded RNA viruses are responsible for causing plant diseases and are referred to as mosaic viruses.

Answer: C 
 This statement is false. Retroviruses are able to regenerate themselves by reverse transcription.

Answer: D 
 This statement is false. Negative-sense single-stranded RNA viruses typically have a relatively small genome, typically fewer than 20,000 base pairs.

Answer: E 
 This statement is false. While the plasma membranes of negative-sense single-stranded RNA viruses may have unique features, they do not have distinct lipids.
