DNA Sequence Visualization
نویسنده
چکیده
This chapter introduces various visualization (i.e., graphical representation) schemes of symbolic DNA sequences, which are basically represented by character strings in conventional sequence databases. Several visualization schemes are reviewed and their characterizations are summarized for comparison. Moreover, further potential applications based on the visualized sequences are discussed. By understanding the visualization process, the researchers will be able to analyze DNA sequences by designing signal processing algorithms for specific purposes such as sequence alignment, feature extraction, and sequence clustering, etc.

Visualisation and Comparison of DNA Sequences by Use of Three-Dimensional Trajectories
In this paper, we propose a visualization tool for dexoyribonucleic acid (DNA) sequences by the use of three-dimensional (3-D) trajectories (TDT). In the proposed method, four different nucleotides are assigned by four corresponding positions in the 3-D space, which are equally spaced and the origin is the centroid of four positions. With the distance accumulated from the distances between mult...
متن کاملDNA Data Visualization (DDV): Software for Generating Web-Based Interfaces Supporting Navigation and Analysis of DNA Sequence Data of Entire Genomes
Data visualization methods are necessary during the exploration and analysis activities of an increasingly data-intensive scientific process. There are few existing visualization methods for raw nucleotide sequences of a whole genome or chromosome. Software for data visualization should allow the researchers to create accessible data visualization interfaces that can be exported and shared with...

In recent years, estimation of protein-coding regions in numerical deoxyribonucleic acid (DNA) sequences using signal processing tools has been a challenging issue in bioinformatics, owing to their 3-base periodicity. Several digital signal processing (DSP) tools have been applied in order to Identify the task and concentrated on assigning numerical values to the symbolic DNA sequence, then app...
متن کاملDynamical Visualization of the Dna Sequence and Its Nucleotide Content
Visual inspection can help reveal patterns that would be computationally rather difficult to reveal. We present a program to visualize a DNA sequence and its nucleotide content. The program visualizes either the whole of a given sequence, or specified fragments. It also provides facilities to compare visualizations obtained for different sequences. The program uses three different algorithms fo...
متن کاملGlobal Visualization and Comparison of DNA Sequences by Use of Three-Dimensional Trajectories
In this study, the three-dimensional (3-D) trajectory (TDT) method for deoxyribonucleic acid (DNA) sequence visualization and comparison is proposed. The global view of a DNA sequence in any sizes can be easily graphically represented by a TDT and examined for sequence characteristics. Studies of the TDTs of known DNA sequences and computer-generated sequences reveal significant pattern dispari...
