Web5 mrt. 2024 · Unwinding of the helix during DNA replication (by the action of helicase) results in supercoiling of the DNA ahead of the replication fork. This supercoiling increases with the progression of the replication fork. If the supercoiling is not relieved, it will physically prevent the movement of helicase.
