In the present work we studied the initial part of thermal denaturation curves of B. subtilis DNA in normal and heavy water, observing, by electron microscopy, the "opening" of DNA as a function of temperature. The results support the hypothesis that D(2)O plays a stabilizing role on strands separation during thermal denaturation of DNA.
Izzo et al. (Wed,) studied this question.
