Statistical Properties of Metastable Intermediates in DNA Unzipping

Author(s): J. M. Huguet, N. Forns, and F. Ritort
We unzip DNA molecules using optical tweezers and determine the sizes of the cooperatively unzipping and zipping regions separating consecutive metastable intermediates along the unzipping pathway. Sizes are found to be distributed following a power law, ranging from one base pair up to more than a …
