Dinucleotide over- and under-representation in complete bacterial genomes (Bacteria and Archaea)

Leonor Palmeira

Statistical analysis of the representation of oligonucleotides has been widely used to try and shed light over sequence structure -- to try and determine the degree in which randomness and selection play a part within biological sequences. In order to understand these features, we conducted a systematic study of the over- and under-representation of dinucleotides in completed Bacteria and Archaea genomes. In this talk, we will first present the general statistical methodology used. We will then discuss some main results.
