基因组特征的自相似性极限
Self-Similarity Limits of Genomic Signatures
摘要:
结果表明,DNA序列的度量表示是一一对应的。通过使用度量表示方法,确定DNA序列中核苷酸串的抑制。对于DNA序列,通过消除有限序列的影响,得到了在混沌博弈表示中显示基因组签名的最佳串长。在计算信息维数时,进一步将光弦长度表示为自相似极限.本发明进一步确定了细菌全基因组签名的自相似性极限。
英文摘要:
It is shown that metric representation of DNA sequences is one-to-one. By using the metric representation method, suppression of nucleotide strings in the DNA sequences is determined. For a DNA sequence, an optimal string length to display genomic signature in chaos game representation is obtained by eliminating effects of the finite sequence. The optical string length is further shown as a self- similarity limit in computing information dimension. By using the method, self-similarity limits of bacteria complete genomic signatures are further determined.
