Mitochondrial Evidence on the Phylogenetic Position of Caecilians (Amphibia: Gymnophiona) [PDF]
Genetics, 2000 AbstractThe complete nucleotide sequence (17,005 bp) of the mitochondrial genome of the caecilian Typhlonectes natans (Gymnophiona, Amphibia) was determined. This molecule is characterized by two distinctive genomic features: there are seven large 109-bp tandem repeats in the control region, and the sequence for the putative origin of replication of ...
