Figure 7.
NRSE distribution in vertebrate and invertebrate genomes. (A) The number of NRSE2 matches in mammalian genomes is relatively constant and includes a significant number of matches within repeats when compared with other vertebrates and compared with the virtual absence of NRSE2 matches in invertebrates. (B) The higher density of all NRSE matches/Mb of genomic sequences in pufferfish and zebrafish when compared with chicken suggest that fish and mammalian NRSE matches may have been expanding independently. Refer to Supplemental Table 5 for the number of matches and the genome size for each genome.
