From the D-(GCAAACGTTTGC)2 B-DNA dodecamer resolved in PDB file 1HQ7 (Fig.
For systems derived from B-DNA stacks, if we seek to describe load flow, it is possible to perform calculations with larger basis sets such as, 6-311++g**, because they have built-in polarization and diffuse functions.
It is known that in a Bto-A transition, the B-DNA
marker band at 835 (phosphodiester mode) shifts toward a lower frequency at -800 [cm.
