The symmetries of the genetic code of mammalian mitochondria.
The genetic code of mammalian mitochondria presents some symmetric in the sequences of certain codons and in the relationships existing between the codons and aminoacids. These symmetries suggest the classification of codons in four classes and indicate that the evolution of the genetic code developed in four stages.
