Q:	A researcher is working to create a targeted therapy for a specific retrovirus. Which of the following provides a reason that using a nonselective RNA splicing enzyme as a medication may not work as an effective drug?

RNA splicing is an important component for retrovirus action, and thus would activate the virus further

retroviruses do not contain RNA

retroviruses would likely evolve and become immune to such therapy

the enzyme would also splice host RNA
