## Abstract Of the two known families of doubleβstranded DNA conformations, A is stable in lessβpolar, and __B__ in moreβpolar solutions. In some waterβnonelectrolyte solutions, __B__ to __A__ transition occurs when water activity in the system is near 0.8. In such systems, however, as waterβmethan
## Synopsis A quantity, called the linking number, is defined, which specifies the total number of t,wists in a circular helix. The linking number is invariant under continuous deformations of the ring and therefore enables one to calculate the influence of superhelical structures on the secondary
