A novel unexpected use of a graphical representation of DNA : Graphical alignment of DNA sequences

Abstract We outline an unexpected use of a particular graphical representation of DNA sequences, the ‘four line’ graphical representation [M. Randic, M. Vracko, N. Lers, D. Plavsic, Chem. Phys. Lett. 368 (2003) 1] and how it can facilitate solving problem of DNA sequence alignment. The approach is exemplified by two shorter DNA sequences.
