WebApr 12, 2024 · Topoisomerases: The great untanglers. DNA forms a double helix. In other words, it’s two long chains twisted together. And for DNA to replicate, it needs to unwind these strands. As this happens, there’s a good chance that the strands will get tangled up. Anyone who’s ever tried to pull a cable out of a drawer full of cables will understand. WebAbstract. Like any genome, mitochondrial DNA (mtDNA) also requires the action of topoisomerases to resolve topological problems in its maintenance, but for a long time, …
