Figure 4.

Genomic organization of AaCA1 and cDNA classes identified for AaCA1 and AaCA2. A, AaCA1 consists of four exons (shaded boxes). Start of translation is indicated with an ATG and the end of translation is labeled “stop.” The positions of the three polyadenylation sites are shown along the 3′ end of the fourth exon. B, Both AaCA1 and AaCA2 can be polyadenylated at alternative sites. Different cDNA size classes (short, medium, and long) and number of clones identified for each class are given.
