[Fluctuation of the incidence of the 4 bases along the mitochondrial genome of mammals using correspondence factorial analysis].
Correspondence analysis has allowed us to reveal a constraint exerting its influence on all of the codons, whatever the amino acid: the probability of use of one codon ending by C varies along the genome. This probability is maximum near the "D-long" and decreases following the heavy strand in the 5'-3' direction. It reaches a minimum in the region diametrically opposite to the "D-loop". This phenomenon is found unchanged for the human, bovine and mouse even though the proportions of T and C at the third portion of the codon varies a lot from one species to the other.
