Factors determining the deriving forces of DNA formation: Geometrical differences of base pairs, dehydration of bases, and the arginine assisting

Article Abstract:

The analysis of the various factors influencing the deriving forces of the DNA formation shows that the geometrical differences of the base pairs, the dehydration of the bases and the assistant of arginine highly affect the process. The results demonstrate that the differences in the base pairs and the use of arginine lead to the extension of the mispairs, as it increases the Gibbs free energy and hence increases the driving force for the DNA formation.

Sharp melting of polymer--DNA hybrids: An associative phase separation approach

Article Abstract:

The sharp melting behavior of the various polymer--DNA hybrids is analyzed and investigated by using a newly developed associative equilibrium theory that studies the phase separation of the hybrids at different temperatures. The results prove that the melting temperature is much higher than that of unattached DNA in solution, as the dense phase dissolves with an increase in the temperature and the salt concentration.

Intercalative stacking: a critical feature of DNA charge-transport electrochemistry

Article Abstract:

Efficient electrochemistry in DNA films requires intercalation of the redox probe. This constitutes another class of experiments that demonstrate long-range DNA charge transport.
