The Amazing Topoisomerase Molecular Machine Youtube Previous video untangler of knots: the amazing topoisomerase molecular machine. topoisomerase ii is an extremely important enzyme in your cells that is designed to untangle knots and supercoils in dna strands that arise during replication and transcription. The topoisomerase ii enzyme is designed to untangle knots and supercoils in dna strands which arise during replication and transcription. it does this by grabbing two tangled dna segments, holding one steady while it breaks the other segment in two, and then passing the first segment through the break. the second segment is then reconnected. A knot near the end of a stretched dna molecule is driven toward the end and unties, leaving an unknotted molecule. (image: alex klotz) the mit team found that they could manipulate knots in these pinned dna molecules by varying the strength of the electric field. when the field is weak, knots tend to move along the molecule toward the closer end. These “scissors” are in every cell of every cellular creature?they both cut and paste with accuracy? in trillions of cells world wide at every replication?w.
