Before revision: We emphasize that assuming the ]  existence of an elongated, hybridized form of DNA ('S-DNA') does not immediately imply DNA overstretching to consist of the complete or near-complete conversion of the molecule from B- to S-form.
After revision: We emphasize that assuming the ] provide a detailed spatial picture of overstretched DNA, showing that under certain conditions the two strands of the double helix separate at about 65 pN. It was proposed that this observation rules out the existence of an elongated, hybridized form of DNA ('S-DNA') does not immediately imply DNA overstretching to consist of the complete or near-complete conversion of the molecule from B- to S-form.
