However, these formulas have typically failed to consider the stretchiness of the molecule. In a new study, published this week in The Journal of Chemical Physics, scientists have derived a formula to determine the end-to-end distance of a semiflexible polymer, including DNA or RNA, while taking into account how much the polymer stretches.

The study was the cover story in the journal Chemical Science.
