Description
Summary:The helical coil is ubiquitous in biological and natural systems, and it is often the basic form in complex structures. This paper considers the question of its dimensionality, , in biological information as the helical coil goes through recursive coiling as in DNA and RNA molecules in chromatin, in which the -value is a function of the lengthening of the curve. It is shown that the dimensionality of coiled coils is virtually equal to . Of the three forms of DNA, the dimensionality of the B-form is nearest to the optimal value, and this might be the reason why it is most common.
