Abstract

The stop signals are nucleotide triplets, TAA, TAG, and TGA found on the first, second, and third reading frames of an open reading frame. The organization of bacterial stop signals may be a result of adaptation of individual species. A detail study of these signals and their relationship with their corresponding dicodons and dipeptides were analyzed in a broad range of bacterial genome. We classified each of these nine stop signals in a broad range of bacterial genomes. Results suggested that some of the stop signals are the result of codon bias due the chromosomal GC content. However, dicodon- and dipeptide- biases are also responsible for the formation of some stop signals.
