    Snippet: To further strengthen this observation and to identify the precise position of the nucleotide modification, we performed primer extension assays on RNA isolated from either SINV-infected HEK293 or Vero cells (Fig. 4C ). 2=-O-methylation can cause reverse transcriptase to pause one nucleotide before and/or at the O-methylated nucleotide. Indeed, we identified two bands (RT stops) that correspond to nucleotides G 8334 and A 8333 , the latter corres.....
    Document: To further strengthen this observation and to identify the precise position of the nucleotide modification, we performed primer extension assays on RNA isolated from either SINV-infected HEK293 or Vero cells (Fig. 4C ). 2=-O-methylation can cause reverse transcriptase to pause one nucleotide before and/or at the O-methylated nucleotide. Indeed, we identified two bands (RT stops) that correspond to nucleotides G 8334 and A 8333 , the latter corresponding precisely to the 3= end of the SvsRNA-1 sequence (Fig. 4C) .
