Abstract

Arita and Kobayashi proposed a method for constructing comma-free DNA codes using binary templates, and showed that the separation d of any such binary template of length n satisfies d==11n/30. Here we demonstrate the existence of an infinite family of binary templates with dn/2-(18nlog"en)^1^/^2. We also give an explicit construction for an infinite family of binary templates with dn/2-19n^1^/^2log"en.
