Ancestral Ixodes spp. D3 and H14 transcript. (A) Location of mutations (excepting I. persulcatus). Arrows point to positions of base substitutions. Wedges and numbers indicate positions and sizes of insertions. Encircled bases indicate where deletions occurred. Stems S1–S4 and H14 are labelled. (B) Transcript sequence that would remain after deletions (indicated by arrows with number of deleted bases) and insertions (indicated by pie sectors) that characterize I. persulcatus.
