Description:
Mathew-Fenn et al. (Reports, 17 October 2008, p. 446) reported unexpected distance fluctuations in short end-labeled DNA constructs and interpreted them as evidence for cooperative DNA stretching modes. We show that when accounting for a subtle linker leverage effect, their data can be understood within standard noncooperative DNA elasticity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Becker, Nils B -- Everaers, Ralf -- New York, N.Y. -- Science. 2009 Jul 31;325(5940):538; author reply 538. doi: 10.1126/science.1168786.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre Blaise Pascal et Laboratoire de Physique, CNRS UMR 5672, Ecole Normale Superieure, Universite de Lyon, 46 Allee d'Italie, 69007 Lyon, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19644093" target="_blank"〉PubMed〈/a〉
