Methods of adding polymers to ribonucleic acids

Abstract

Provided are methods of adding a polymer of non-canonical nucleotides to the 3′ end of a ribonucleic acid (RNA). In certain embodiments, the methods comprise combining an RNA, a polynucleotide-3′ nucleotidyl transferase, and non-canonical nucleotides, in a reaction mixture under conditions in which the polynucleotide-3′ nucleotidyl transferase adds a polymer of the non-canonical nucleotides to the 3′ end of the RNA. Such methods may further include analyzing the RNA using a nanopore. According to some embodiments, the methods include identifying the polymer of non-canonical nucleotides added to the 3′ end of the RNA, and determining the junction between the 3′ end of the RNA and the polymer of non-canonical nucleotides to identify the 3′ end of the RNA. Kits that find use, e.g., in practicing the methods of the present disclosure are also provided.
