Abstract: | We have applied the newly developed hierarchical structure theory for complex systems to analyze the multi-scaling structures
of the nucleotide density distribution along a linear DNA sequence from the completeEscherichia coli genome. The hierarchical symmetry in the nucleotide density distribution was demonstrated. In particular, we have shown that
the G, C density distribution that represents a strong H-bonding between the two DNA chains is more coherent with smaller
similarity parameter compared to that of A, T density distribution, indicating a better organized multi-scaling fluctuation
field for G, C density distribution along the genome sequence. The biological significance of these findings is under investigation. |
