title: Codon catalog usage is a genome strategy modulated for gene expressivity.
abstract: The nucleic acid sequence bank now contains 161 mRNAs, 43 new genes are added. One sequence, that of B. mori fibroin, is dropped due to uncertainty on the starting point for translation. Frequencies of all codons are given for each gene added and for each genome type in the total bank. A new series of correspondence analyses on codon use is presented, substantiating the genome hypothesis. Internal regulation of mRNA expression by different third base choices between quartet and duet codons is proposed for bacterial genes.
