Polymerase chain reaction (PCR) followed by sequencing of single-stranded DNA yielded
sequence information from the cytochrome b (cyt b) region in mitochondrial DNA from the …

The internal transcribed spacer (ITS) of the ribosomal DNA is generally considered to be
under low functional constraint, and it is therefore often treated as a typical nonfunctional …

Phylogenetic analyses of mitochondrial DNA (mtDNA) sequences were used to assess the
matriarchal genetic structure of the threespine stickleback, Gasterosteus aculeatus. A 747 …

The entire nucleotide sequence of the mitochondrial genome of the American opossum,
Didelphis virginiana, was determined. Two major features distinguish this genome from …

A combination of polymerase-chain-reaction amplification and automated DNA sequencing
was used to survey variation in a species complex of pest insects, the spruce budworms …

Most fishes of the perciform suborder Notothenioidei are endemic to the subzero marine
waters of Antarctica. A number of remarkable physiological attributes allow them to inhabit …

Substitution-rate variation among sites and differences in the probabilities of change among
the four nucleotides are conflated in DNA sequence comparisons. When variation in rate …

To test hypotheses of neutral evolution of mitochondrial DNA (mtDNA), nucleotide
sequences were determined for 1515 base pairs of the NADH dehydrogenase subunit 5 …

From the cloned mitochondrial DNAs (mtDNAs) isolated from two bisexual species, one
Mediterranean, Artemia salina, and one American, Artemia franciscana, and two …

Compositional bias, the occurrence of the four bases in unequal proportions, is a common
feature of nucleotide sequences. We analyzed patterns of character-state reconstruction …
