What is the function of DNA gyrase?
A)Connects Okazaki fragments by sealing nicks in the sugar-phosphate backbone
B)Unwinds the double helix by breaking the hydrogen bonding between the two strands at the replication fork
C)Reduces the torsional strain that builds up ahead of the replication fork as a result of unwinding
D)Binds to oriC and causes a short
E)Prevents the formation of secondary structures within single-stranded DNA

Question

DNA gyrase reduces the torsional strain that builds up ahead of the replication fork as a result of unwinding. It does this by breaking and rejoining the double helix, allowing it to rotate and release the tension.
