Figure 5

Multiple alignment showing sequence and positional conservation of the NRG element in intron 1–2 of the succinate dehydrogenase [ubiquinone] cytochrome B small subunit gene in Drosophilidae (A) and in A. gambiae and A. aegypti (B). Alignments are based on Multalin alignments [34] using default parameters for DNA sequences. Red indicates conservation throughout the species examined; blue indicates lesser but still significant conservation. NRG motifs are highlighted in yellow; vertical bars indicate exon/intron boundaries.
