摘要

THE study of the relations between the topological structure and its function is one of the focuses in modern chemistry and life science. In this note we set up a topological model to describe the ccDNAs on the basis of Seifert construction in knot theory. Our model for the ccDNAs helps to determine whether a structure is topologically chir al or achiral. This is one of the fundamental biological problems.
