Numerical representation of DNA sequences

Abstract: DNA sequence analysis using digital signal processing requires conversion of a base sequence to a numerical sequence. The choice of the numerical representation of a DNA sequence affects how well its biological properties can be reflected in the numerical domain for the detection and identification of the characteristics of special regions of interest. This paper presents some selected methods of DNA numerical representation for DNA sequence analysis, discusses their relative merits and demerits, and includes … Show more

“…The second choice is based on the geometric representations where meaningful real or complex numbers are assigned to the four characters A, T, G, and C. In this way a single numerical sequence representing the entire character string is obtained. In general FM techniques [5] include the Voss [7], the tetrahedron [2], the complex [8]- [11], the integer [9], the real [12], and the quaternion [13] - [14] representations. Each of the DNA numerical representations offers different properties as will be show in details in the following sections.…”

“…Other representations include the quaternion approach [15], the electron-ion interaction potential method [20], real-number representation [21], complex number mapping [22], etc. The most commonly used method in spectrum analysis is the discrete Fourier transform (DFT) [23], as shown in Eq.…”

“…Such a mapping is called numerical representation and its choice affects how well the biological properties of a nucleotide sequence can be revealed in numerical domain. A nucleotide sequence can be numerically represented in the form of R-sequence, a survey on mappings with R ≥ 1 is given in [3,4]. 1-sequence numerical representation (with R = 1) is the most compact form of mapping in which one nucleotide is mapped to one fixed numerical value to form a single sequence.…”
