35) Refer to the treatments listed to answer the question. You isolate an infectious substance capable of causing discase in plants, but you do not know whether the infectious agent is a bacterium, virus, or prion. You have four methods at your disposa to analyze the substance and determine the nature of the infectious agent. I.

would you please help me filling the blanks! The methyl group in thymidine has been replaced by an iodine atom 12.3.1 Nucleoside analogues Antiviral therapy is aimed at preventing viral DNA from being replicated within the host cell. The strategy is to use molecules which resemble natural nucleosides but which are modified to make them nonfunctional. These are called mucleoside analogues.
