Abstract
We investigate numerically the mechanics of a simple lattice model of DNA. The model consists of two linear-mass chains connected by a Morse potential representing the hydrogen bonding between the sugar-phosphate backbones. Effects on discrete breather-type solutions caused by random noise and mass defects, representing interaction with the local environment, are studied.Keywords
