    摘要: A method for determining the pattern of nonrandom codon pair usage of an organism, comprising the steps of obtaining nucleotide sequence data for the organism, determining from the data the number of codons represented in at least a portion of the sequence and the frequency of usage of at least some codons in the portion, determining from the frequency the expected number of occurrences of at least some codon pairs, if they are paired in a random manner, and comparing the expected number with the actual number of occurrences to determine relative codon pairing preferences. The codon pairings of organisms are highly nonrandom, and differ from organism to organism. This information is used to construct and express altered or synthetic genes having desired levels of translational efficiency, to determine which regions in a genome are protein coding regions, to introduce translational pause sites into heterologous genes, and to ascertain relationship or ancestral origin of nucleotide sequences.
