Reversible conformational transitions
- Melting
- DNA packaging
- DNA bending induced by
ligand binding
- B-Z transition (right-left
winding)
DNA-bleomycin complex
- 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
Transformation of DNA tertiary structure can be induced by different procedures:

Conclusions (part 1)
- Gene vectors can be formed at definite relation
- f 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
