  7. Reversible conformational transitions • Melting • DNA packaging • DNA bending induced by ligand binding • B-Z transition (right-left winding) DNA-bleomycin complex

  8. Transformation of DNA tertiary structure can be induced by different procedures: • Phosphate group screening • Change in DNA charge density (by pH variation, ionic bonds with phosphates) • Variation in solvent quality (by the addition of alcohol or other poor solvent into DNA-water solution) • Binding with ligands (alteration in DNA hydrophility, conversion of charge density, decrease of DNA rigidity) • Intramolecular reorganization via simultaneous influence of counterions and conversion of solvent properties

  17. Conclusions (part 1) • Gene vectors can be formed at definite relation of polycation/DNA concentration (N/P) • DNA condensation is realized at N+/P>1 • DNA-polycationic gene vectors (D=120 nm) can penetrate into cell and can provoke the protein production • AFM and Dynamic Light Scattering belong to rare appropriate methods for the monitoring of condensed DNA structure. • AFM images correctly reflect DNA conformation in complexes with polycations
