supercoil


supercoil
The conformation of a double-stranded DNA molecule placed under torsional stress as a result of interactions with proteins. The stress is accommodated by a twist imposed on the duplex. A left-handed supercoil favours unwinding of the double helix; a right-handed supercoil favours tighter winding.
