Topoisomerase, which untangles DNA. My understanding is if you pull separate strands, Topoisomerase finds the local the crossing points that are under pressure and unties them by cutting and gluing. After being cut and before being glued, the DNA stays attached to the Topoisomerase, so the double strand doesn’t just fall apart.
Thanks for spotting! Fixed!
Nucleosomes
help of course, but I was thinking of
