Variations in the genetic code are found frequently in mitochondrial decoding systems. Four
non-universal genetic codes are employed in ascidian mitochondria: AUA for Met, UGA for …

Non-universal genetic codes are frequently found in animal mitochondrial decoding
systems. In squid mitochondria, four codons deviate from the universal genetic code, namely …

The genetic code is not frozen but still evolving, which can result in the acquisition
of'dialectal'codons that deviate from the universal genetic code. RNA modifications in the …

In animal mitochondria, six codons have been known as nonuniversal genetic codes, which
vary in the course of animal evolution. They are UGA (termination codon in the universal …

Amino acid assignments of metazoan mitochondrial codons AGA/AGG are known to vary
among animal species; arginine in Cnidaria, serine in invertebrates and stop in vertebrates …

It has been inferred from DNA sequence analyses that in echinoderm mitochondria not only
the usual asparagine codons AAU and AAC, but also the usual lysine codon AAA, are …

In squid (Loligo breekeri) mitochondria, AUA codons are translated as methionine instead of
the universal isoleucine. Here, we present the nucleotide sequence of squid mitochondrial …

In mitochondria of the squid, Loligo bleekeri, both the AGA and AGG codons are considered
to correspond to serine instead of arginine as in the universal genetic code, and its genome …

In the starfish mitochondrial (mt) genome, codons AGA and AGG (in addition to AGU and
AGC) have been considered to be translated as serine. There is, however, only a single …

The H-strand of vertebrate mitochondrial DNA is left single-stranded for hours during the
slow DNA replication. This facilitates C→ U mutations on the H-strand (and consequently …
