We have used the asymmetry between the coding and noncoding strands in different codon positions of coding sequences of DNA as a parameter to evaluate the coding probability for open reading frames (ORFs). The method enables an approximation of the total number of coding ORFs in the set of analyzed sequences as well as an estimation of the coding probability for the ORFs. The asymmetry observed in the nucleotide composition of codons in coding sequences has been used successfully for analysis of the genomes completed at the time of this analysis.
