Many antiviral drugs are nucleoside analogs.The nucleoside analogs primarily target these enzymes

Question

Quizplus · Accepted Answer

Nucleoside analogs are synthetic compounds that resemble the structure of nucleosides (building blocks of DNA and RNA) and are incorporated into the viral nucleic acid by viral nucleic acid polymerases during replication, thereby disrupting the synthesis of viral DNA or RNA. Host cell DNA or RNA polymerases are not targeted as their structures are too different from viral nucleic acid polymerases. Host cell nucleases and viral nucleases are enzymes responsible for the degradation of nucleic acids and are not directly targeted by nucleoside analogs.
