A new graphical representation of protein sequences based on dual-vector model

Graphical representation of protein sequences is an important method of sequences analysis. We propose a new graphical representation of protein sequences with Virtual DNA Codon and DV-Curve. With virtual DNA codon, we successfully retranslate a protein sequence to a virtual DNA sequence. And then we use DV-Curve to visualize the virtual DNA sequence. The new graphical representation avoids degeneracy and loss of information. It also has good visualization even sequences are long, and avoids the difficulty of observing in multi-dimensional graph.
