Scale-invariant spatial patterns in genome organization

Research output: Contribution to journal › Article › peer-review

Abstract

Eukaryotic genomes are characterized by coding regions interspersed within non-coding sequences, creating irregular dispersal patterns. Fractal analysis was applied to the study of this dispersed organization of eukaryotic genomes. The results show that eukaryotic genomes possess two length regimes - a short ordered length scale, and a fractal regime with fractal dimensions ranging from 0.21±0.02 to 0.84±0.02. Fractal scaling provides clues to the origin and evolution of sequence patterns within genomes, and provides us with tools necessary to characterize such patterns in detail.
