Fig. 3From: Intermediate introns in nuclear genes of euglenids – are they a distinct type?Sequence logos. a Sequence logos of exon/intron junctions of nine homologous nonconventional introns. b Sequence logo of exon/intron junctions of all 55 analyzed nonconventional introns; introns in different forms of the gene from the same strain not included. Exons shaded in dark gray; conserved nucleotides CAG/CTG at positions +4, 5, 6/-8, 7, 6 shaded in light grayBack to article page
