A simple method encoding linear single strain DNA sequence with natural numbers

A simple method presenting linear single strain DNA (LssDNA) sequence with natural numbers is introduced in this paper. The method presents LssDNA correspondingly with the numerals 1, 2, 3 and 4. After calculation, the sequence can be coded in natural numbers which can also be decoded into the DNA sequence. Thus, an LssDNA sequence can be expressed in a natural number and a dot at coordinate axes. In the future, a new LssDNA sequences database termed “DotBank” would be realized in which each LssDNA sequence is determined as a dot.
