The study of reproductive isolation and species barriers frequently focuses on mitochondrial
genomes and has produced two alternative and almost diametrically opposed narratives. On …

The mitochondrion was originally a free-living prokaryotic organism, which explains the
presence of a compact mammalian mitochondrial DNA (mtDNA) in contempory mammalian …

The 4,639,221–base pair sequence of Escherichia coli K-12 is presented. Of 4288 protein-
coding genes annotated, 38 percent have no attributed function. Comparison with five other …

One of the most important aspects of mitochondrial (mt) genome evolution in Metazoa is
constancy of size and gene content of mtDNA, whose plasticity is maintained through a great …

Neuroptera (lacewings) and allied orders Megaloptera (dobsonflies, alderflies) and
Raphidioptera (snakeflies) are predatory insects and together make up the clade …

The base composition of 25 complete mammalian mitochondrial (mt) genomes has been
analyzed taking into account all three codon positions (P1230 and fourfold degenerate sites …

A novel method of cumulative diagrams shows that the nucleotide composition of a microbial
chromosome changes at two points separated by about a half of its length. These points …

Strand asymmetry in nucleotide composition is a remarkable feature of animal mitochondrial
genomes. Understanding the mutation processes that shape strand asymmetry is essential …

Ladybirds (family Coccinellidae) are one of the most diverse groups of beetles and globally
comprise over 6000 species. Despite their scientific and economic significance, the …

The entire mitochondrial genome of the tobacco hornworm, Manduca sexta (Lepidoptera:
S**hidae) was sequenced—a circular molecular 15516 bp in size. The arrangement of …
