Fig. 2.

Multiple alignments of the terminal regions of the coding strands of dsRNAs 1–8. a, b Conserved sequences of the 5′- and 3′-termini of the dsRNAs, respectively. Black, gray, and light gray backgrounds denote a nucleotide identity of no less than 100%, 80%, and 60%, respectively. The terminal nucleotides together with their frequencies in the RACE experiments are indicated adjacent to the strand ends
