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: Recent experiments ] 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.
