The human genome: a multifractal analysis

Abstract: BackgroundSeveral studies have shown that genomes can be studied via a multifractal formalism. Recently, we used a multifractal approach to study the genetic information content of the Caenorhabditis elegans genome. Here we investigate the possibility that the human genome shows a similar behavior to that observed in the nematode.ResultsWe report here multifractality in the human genome sequence. This behavior correlates strongly on the presence of Alu elements and to a lesser extent on CpG islands and (G+C) c… Show more

“…FD takes on non-integer values between the classical Euclidean dimensional values of one, two and three used to define the dimensions of a line, square and a cube. Fractal geometry has been used to describe molecular folding of DNA, and the nucleotide distribution in the genome [16][17][18][19]. In such instances, FD explains the complex structural organization of natural objects.…”

“…The high multifractal chromosomes have the highest densities of Alu elements and genes per Mb (Moreno, et al, 2011). Particularly chromosomes 17 and 19 are by far, the most multifractal chromosomes have the highest gene densities of the whole genome and a high and medium frequencies of lentiviral integration.…”

“…The chromosomal localization of the lentiviral provirus included in the present study was performed by using the G pattern banding of each chromosome according with the International System for Human Cytogenetic Nomenclature -ISCN- (Simonis, et al, 2006). The mean values of multifractality (AvΔDq) per each chromosome were obtained from the analysis of the multifractality that included 9,389 genomic fragments of 300 Kb each one, representing 2,816,700 Kb covering more than 98.6% of the human genome (Moreno, et al, 2011).…”

“…En este proyecto (AMGH) se aplicaron diferentes técnicas y herramientas de Bioinformática y de Geometría Fractal para la construcción de un modelo teórico, no lineal e "integrativo" que explica cómo se estructura y funciona el genoma humano (ver principales resultados del proyecto en [6] y [7]). Este estudio se adelantó a partir de la información del genoma humano publicada en el GenBank [2,5] y la gestión de datos también se basó en archivos planos, heredando de esta forma los problemas mencionados previamente.…”
