The methods of elasticity theory were used to simulate topological properties of supercoiled DNA. A mechanism of realization of topological restrictions for supercoiled DNA was established. A possibility of transition from right hand to left hand DNA in strand molecules was theoretically proved. Influence of a corner strand on topological characteristics of a molecule was investigated. The parameters of force contact interaction in branches strand were defined.

Keywords: topologic, corner strand, right helical–left helical transition, force characteristics.
