Explain the action of nucleoside analogues as antiviral agents.
Answers
Nucleotide analogs are nucleotides which contain a nucleic acid analogue, a sugar, and one to three phosphate groups. Nucleoside and nucleotide analogues can be used in therapeutic drugs, include a range of antiviral products used to prevent viral replication in infected cells.

Nucleoside and nucleotide analogues can be used in therapeutic drugs, include a range of antiviral products used to prevent viral replication in infected cells. The most commonly used is acyclovir, although its inclusion in this category is uncertain, because it acts as a nucleoside but contains no actual sugar, as the sugar ring is replaced by an open-chain structure.
