The Linking number (Lk) is the number of times the axis of a DNA molecule crosses itself around the central axis. Lk determines the degree of supercoiling. The linking number of DNA molecule cannot change until the two strands are covalently intact. It can only be changed by breaking and rejoining of strands.
