33.Homologous Sequences in Other Species


Once we cloned cDNAs encoding the human A transferase, we used one of these cDNAs to probe homologous sequences in the genomes of other species of organisms. We observed weak signals in chicken genomic DNA and strong signals in all mammalian species tested (Kominato et al., 1992). Surprisingly, we found strong genomic DNA signals in dog, cat, and rabbit samples – signals as strong as those in humans.
