Before revision:  We obtain parameters of the model from the all atom AMBER force field. The model can be used to study large local deformations of long DNA molecules (for example, in binding with proteins) . Small modification of the model can provide the possibility of modeling base pairs openings in melting, transcription and replication. And one can also simulate the interactions of the DNA molecule with different types of ions in different kinds of solutions .
After revision:  With these features, the sugar CG DNA model reproduces (with the same parameters) both the B- and A- stable forms under corresponding conditions and demonstrates both the A to B and the B to A phase transitions .
