title: Circular codes in archaeal genomes.
abstract: A new statistical method associating each trinucleotide with a frame is developed for identifying circular codes. Its sensibility allows the detection of several circular codes in the (protein coding) genes of archaeal genomes. Several properties of these circular codes are described, in particular the lengths of the minimal windows to retrieve the construction frames, a new definition of a parameter for measuring some probabilities of words generated by the circular codes, and the types of nucleotides in the trinucleotide sites. Some biological consequences are presented in Discussion.
