title: Bending of short DNA helices.
abstract: In their recent Science paper, Vafabakhsh and Ha claim that DNA duplexes at the range of 100 bp experience anomalous flexibility, much greater than the flexibility of large DNA molecules. ( 1) However, careful reevaluation of their data leads to the conclusion that the presented data do not warrant the authors' claim.
