(A) The fog-1 gene family. (B) The cpb-2 family. Changes in splicing structure in the fog-1 and cpb-2 genes. We cloned cDNAs as described in the Methods section, and determined gene structures by comparing cDNA and genomic DNA sequences. Protein-coding regions are shown as black boxes, noncoding regions as gray boxes, and introns as thin lines. The SL1 leader sequence is shown as a small exon located above the line. All genes were drawn to scale.
