[Supercoiled DNA: geometry, topology, and B-Z-transitions]. 2009

A N Kamliuk, and A V shirko

The geometrical characteristics of a DNA molecule in a supercoiled state has been analyzed. The possibility of the B-Z-transition in the strand of the DNA molecule has been established. The influence of the corner strand on differential-geometric and topological characteristics of the DNA molecule has been investigated.
