Figure 16

Alignment of a tunicate, two Caenorhabditis and Anopheles , a Drosophila , and six vertebrate GNB1 AA sequences. The portions of intron insertion sites are illustrated by changes in colors of AA code characters. Red to black transition or vise versa is the case for the intron insertion that occurred between two neighboring AA codes (phase 0 intron). Green and sky blue indicate phase 1 intron and phase 2 intron, respectively. The upper 7 taxis are deuterostomes, and the lower 4 are protostomes. Alignments were performed by the ClustalX 1.83 program. The lowest line indicates Clustal Consensus with stars and dots.
