Fig. 7. TT motif codons are not conserved. A) Exon sizes from KS with known genomic sequence. B) Sequence of TT motif containing exon from AtKS (codons for TT motif in larger blue text). C) Sequence logo indicating lack of conservation of the codons for the TT motif – i.e., in the variable third/'wobble' position.
