Changes of conformation of DNA produced by mechanical forces.
It is shown that when tension is applied to DNA it can change its conformation. In the relaxed state, DNA adopts the A form in the absence of excess salt. When tension is applied, either the B, C or stretched conformations of DNA are observed, depending on the humidity of the sample.
