Exoribonuclease-Resistant RNAs Exist within both Coding and Noncoding Subgenomic RNAs

Abstract excerpt

During infection, viruses often produce subgenomic RNAs (sgRNAs) that either serve as the template for protein synthesis or act as "riboregulators" that interact with and influence the viral and cellular machinery. Recently, a mechanism for producing sgRNAs was found that depends on the presence of specifically structured RNA elements (xrRNAs). However, the degree to which this mechanism is used, where the...
