WebBase analogs are derivatives of the normal DNA bases, which may mimic to varying extents the properties of the normal bases. As such, they have the ability to interfere with normal nucleotide metabolism and exert a variety of toxic and mutagenic effects. One example of their application as a toxic compound is usage as antiviral or antitumor agents. WebConcept explainers. Article. Mitochondrial Mutations. arrow_forward.
