摘要: Background Oligonucleotide frequencies were shown to be conserved signatures for bacterial genomes, however, the underlying constraints have yet not been resolved in detail. In this paper we analyzed oligonucleotide usage (OU) biases a comprehensive collection of 155 completely sequenced chromosomes, 316 plasmids and 104 phages.
