| molecular homology assessment and phylogeny in the lizard family opluridae (squamata: iguania). | the effect of utilizing secondary structure on multiple alignment and phylogeny reconstruction was examined for the mitochondrial 12s ribosomal rna and valine transfer rna genes in the lizard family opluridae. computer-generated multiple alignments were performed under parsimony using gap costs of 1-10 both with and without reference to secondary structure. alignments performed without secondary structure resulted in disruption of positional homology in some stems at all gap costs. number of mis ... | 1996 | 8812305 |
