The coding and noncoding length sequences constructed from a complete genome
are characterised by multifractal analysis. The dimension spectrum Dqβ and
its derivative, the 'analogous' specific heat Cqβ, are calculated for the
coding and noncoding length sequences of bacteria, where q is the moment
order of the partition sum of the sequences. From the shape of the
and Cqβ curves, it is seen that there exists a clear difference between the
coding/noncoding length sequences of all organisms considered and a completely
random sequence. The complexity of noncoding length sequences is higher than
that of coding length sequences for bacteria. Almost all Dqβ curves for
coding length sequences are flat, so their multifractality is small whereas
almost all Dqβ curves for noncoding length sequences are multifractal-like.
We propose to characterise the bacteria according to the types of the Cqβ
curves of their noncoding length sequences.Comment: 15 pages with 5 figures, Latex, Accepted for publication in Physica
