Figure 2.

Secondary structures of double stranded 18S sequences. Stitch Profiles calculated at 90.7°C showing melted and double stranded regions for the three new solenogaster 18S sequences and the caudofoveate Scutopus ventrolineatus. One short helical region in the S. ventrolineatus sequence of approximately 100 bp length and 63% GC content is at the same position as in the solenogaster sequences.
