Preprint NCU/CCS-1999-1215; NCTS-99xxxx Frequencies of Oligonucleotides as A Means of Characterizing Organisms


Frequencies of oligonucleotides are used to characterize nucleic sequences. The di erence in frequency distributions of oligonucleotides n bases long in sequences is used to de ne an n-distance between sequences that are not aligned. Phylogenetic trees for 35 organisms, 19 bacteria, 9 archaeons and 7 eukaryotes, are constructed using ndistances, n=2 to 9… (More)
