A Model for manipulating Spirals

Abstract

DARLINGTON1 suggested that the coiling systems encountered in chromosomes are determined by spiral structures at the molecular level. Interest in the replication of spirals and in the separation in double spirals has been renewed recently2–4 following proposals of helical structures for deoxyribonueleic acid2 and for various proteins5. Some of the difficulties in the disentangling of twin spirals are simplified if the spirals are free to rotate about their axes, as may be demonstrated using the simple model here described.
