Table 4. Number of exons of five key miRNA biogenesis genes.
Metazome 3.0 and Ensembl Metazoa v.29 genome browsers were interrogated with the previously analyzed hits for each organism. La and Ap genomes were downloaded and analyzed locally. Mg gene structures were retrieved as described in Methods. In green are reported Protostomia; in orange Deuterostomia.
