Figure 1.

Cartoon representing different forms of catenanes after projection on a plane. (A) One pair of nicked DNA rings catenated once. (B) One pair of nicked DNA rings catenated twice. (C) One pair of DNA rings catenated once where one ring is nicked and the other covalently closed and supercoiled. (D) One pair of DNA rings catenated once where both rings are covalently closed and supercoiled. n = nick; OC = open circle; CCC = covalently closed circle; Ca = catenation number. Parental DNA strands are depicted in blue and green while newly synthesized strands are depicted in red.
