Accepted: 24 May 2007
A quantum spin model representing tautomeric mutation is proposed for any DNA molecule. Based on this model, the quantum-mechanical calculations for mutational rate and complementarity restoring repair rate in the replication processes are carried out. A possible application to a real biological system is discussed.
