Abstract

Various studies of DNA sequences have involved the multifractal analysis. In this paper, we use it to investigate the C.elegans genome gene's composition of exon and intron sequences. First, we generate the gene's frequency chaos game signal (FCGS) signal to transform its DNA sequence text representation into a 1D signal. Next, we use the wavelet transform modulus maxima method (WTMM) to calculate the multifractality degree. We calculate also the percentages of exon and intron sequences present in the gene. The acquired results demonstrate the existence of a relationship between the gene's multifractality and its exon and intron composition. Genes with longer intron sequences than exon sequences are highly multifractal. This approach serves us in the future to frisk and classify automatically anonymous sequences.
