The triplet nature of the genetic code is considered a universal feature of known organisms. However, frequent stop codons at internal mRNA positions in <i>Euplotes</i> ciliates ultimately specify ribosomal frameshifting by one or two nucleotides depending on the context, thus posing a nontriplet feature of the genetic code of these organisms. Here, we sequenced transcriptomes of eight <i>Euplotes</i> species and assessed evolutionary patterns arising at frameshift sites. We show that frameshift ...[more]
