Similarity studies of DNA sequences based on a new 2D graphical representation

Alignment-free comparison of genome sequences by a new numerical characterization

“…On the basis of the above design, we can change a DNA sequence into a graphical curve in the first and fourth quadrants of Cartesian coordinate system using the same method as in Yu et al (2010) and Huang et al (2008Huang et al ( , 2009). Here, we highlighted the difference of four vectors in y-values.…”

DNA sequence comparison by a novel probabilistic method

“…Among all existing alignment-free methods for comparing biological sequences [10,28,23,5,25], sequence graphical representation provides a simple way to view, sort, and compare gene structures [11,13,29,24,18,15,14]. The aim of graphical representation is to display DNA or protein sequences graphically so that we can easily find out visually how similar or 0020-0255/$ -see front matter Ó 2010 Elsevier Inc.

Similarity/Dissimilarity of DNA Sequences Based on a New Condensed Curve Representation

“…Moreover, compared with others' work [1]- [5], [8]- [14], [19]- [28], our graphical curves are compact, that's to say, our graphical curves do not take up much room, and the complexities of computation is very small. Furthermore, the examination of similarities among the full coding sequences of globin gene of different species (see Table I) which were studied by Li et al [15] and Guo et al [29] and Li et al [30] and Qi et al [31] and Huang et al [32] and Guo et al [33] and Qi et al [34] shows our graphical representation method is more effective to the comparative study of DNA sequences.…”
