Multiple studies demonstrate that DNA molecules naturally form complex topological knots and entanglements due to helical structure, replication, and intracellular processes.
The retrieved papers consistently confirm that DNA naturally forms complex knots and entanglements as a byproduct of its double-helical structure, replication, and cellular processing (e.g., papers 0, 2, 4, 5, 11). There are no papers refuting this claim; therefore, the verdict is SUPPORTED.
