Comparison of intron lengths among the axolotl (AM), human (HS), chicken (GG), and frog Xenopus tropicalis (XT) for cleavage and polyadenylation specific factor 5 (NUDT21) and 3-hydroxy-3-methylglutaryl-Coenzyme A reductase (HMGCR). One exon of HMGCR could not be identified in the X tropicalis genome.
