6 Topoisomerase A class of enzymes that alter the supercoiling of doublestranded DNA In supercoiling the DNA molecule coils up like a telephone cord which shortens the molecule The topoisomerases act by transiently cutting one or both strands of the DNATopoisomerase also plays an important maintenance role during DNA replication This enzyme prevents the DNA double helix ahead of the replication fork from getting too tightly wound as the DNA is opened up Bacterial See Answer
