Analysis of genomic sequences by Chaos Game Representation
MOTIVATION Chaos Game Representation (CGR) is an iterative mapping technique that processes sequences of units, such as nucleotides in a DNA sequence or amino acids in a protein, in order to find the coordinates for their position in a continuous space. This distribution of positions has two properties: it is unique, and the source sequence can be recovered from the coordinates such that distan...
متن کاملGenomic signature: characterization and classification of species assessed by chaos game representation of sequences.
We explored DNA structures of genomes by means of a new tool derived from the "chaotic dynamical systems" theory (the so-called chaos game representation [CGR]), which allows the depiction of frequencies of oligonucleotides in the form of images. Using CGR, we observe that subsequences of a genome exhibit the main characteristics of the whole genome, attesting to the validity of the genomic sig...
متن کاملEncoding DNA sequences by integer chaos game representation
Motivation: DNA sequences are fundamental for encoding genetic information. The genetic information may be understood not only by symbolic sequences but also from the hidden signals inside the sequences. The symbolic sequences need to be transformed into numerical sequences so the hidden signals can be revealed by signal processing techniques. All current transformation methods encode DNA seque...

CGR is an effective method for visualizing any structural features if it is given as a sequence of elements [1,2] analyzed by the genomic signature appears as a powerful tool for investigating the mechanisms of DNA maintenance from which the DNA structure results. It would be necessary to understand the patterns they exhibit and to be able to interpret them in a biologically meaningful way [3]....
