covalently-closed circular DNA

covalently-closed circular DNA
Abbreviation: ccc DNA
A DNA molecule in which the free ends have ligated to form a circle. The strands remain linked together even after denaturation. Plasmids exist in this form in their in vivo state. In its native form, ccc DNA will adopt a supercoiled configuration.
