Abstract

Collective coordinate and direct numerical integration methods are applied to the analysis of a one-dimensional DNA model. A modification of the coupling constant in an extended region is found to be less selective towards the breather it can trap than an isolated impurity. Therefore it provides a possible physical mechanism for the effect of an enzyme on DNA transcription.
