Why is it good to keep DNA in the loop?

This could be vital in medicine, like cancer therapy and also in understanding how our cells multiply: researchers have identified a mechanism by which long DNA molecules pack themselves into the tiny space inside a cell.

In 10 seconds? Scientists have untangled a mystery – how DNA forms loops in the nucleus of our cells to avoid being tangled and becoming useless. The process also plays a role in transcribing genetic code into proteins which can occasionally malfunction, leading to diseases.
