| Abstract: | In this paper we study the scaling behavior of nucleotide cluster in 11 chromosomes of Encephalitozoon cuniculi Genome. The
statistical distribution of nucleotide clusters for 11 chromosomes is characterized by the scaling behavior of P(S) ∝ e−αS
, where S represents nucleotide cluster size. The cluster-size distribution P(S
1+S
2) with the total size of sequential C-G cluster and A-T cluster S
1+S
2 were also studied. P(S
1+S
2) follows exponential decay. There does not exist the case of large C-G cluster following large A-T cluster or large A-T cluster
following large C-G cluster. We also discuss the relatively random walk length function L(n) and the local compositional complexity of nucleotide sequences based on a new model. These investigations may provide some
insight into nucleotide cluster of DNA sequence.
