| pancreatic-type ribonuclease 1 gene duplications in rat species. | mammalian pancreatic-type ribonucleases (rnases) 1 represent single-copy genes in the genome of most investigated mammalian species, including mus musculus and other murid rodents. however, in six species belonging to the genus rattus and closely related taxa, several paralogous gene products were identified by southern blotting and pcr amplifications of genomic sequences. phylogenies of nucleotide and derived amino acid sequences were reconstructed by several procedures, with three mus species ... | 2002 | 12399926 |
