Second of two lectures with following content:

1. The "educated guess" of J. Watson and F. Crick (1953) and the first single-crystal X-ray structure (1980)
2. Polymorphism of DNA double helices: B-, A- and Z-type structures.
3. The specificity of natural bases pairing as a designer/building tool
4. Beyond the double helix by "sticky" guanosine self-assembly: quadruple helices and planar ribbons
5. Long distance charge transport through DNA oligonucleotides in aqueous buffer solution
6. DNA enters the material world: the early suggestion of D. Eley and D. Spivey (1962) and the present wealth of experiments
7. DNA as a scaffold for organizing and interconnecting electronic components into nanoelectronic circuits: self-assembly of an electronic device into a test tube
8. "Dry" DNA as a conductive wire. Selected exemples of the many, conflicting reports
9. AFM images of "dried" DNA and Guanosine quadruple helix
