abstract：:Computer analyses of various genome sequences revealed the existence of certain periodical patterns of adenine-adenine dinucleotides (ApA). For each genome sequence of 13 eubacteria, 3 archaebacteria, 10 eukaryotes, 60 mitochondria, and 9 chloroplasts, we counted frequencies of ApA dinucleotides at each downstream pos...
