I know most of the time it is actually folded on itself using special proteins, but it gets constantly “unfolded” to get sequence from it. So. How and why it doesnt turn into a mess like fishing line?

I’m not a scientist but I always thought because it’s a double helix is doesn’t tangle? I could be way off the mark though
there is a special protien that detects knots, and cuts the dna, and then re-joins it unknotted https://researchoutreach.org/articles/dna-untangled-topoisomerase-enzymes/
its also folded up as you mentioned, only a small section gets unfolded at a time, not a really long unfolded string.
