EFFECTS OF METAL IONS ON THE CONFORMATIONAL CHANGES OF DNA

Abstract

Abstract: DNA takes on multi-different conformations such as A-, B-, C-, D- and Z-form. These conformations can transit to one another when DNA deposited in some metal ions solutions or when changing the concentrations of the same metal ions. Here, several major conformational transitions of DNA induced by metal ions under different environment were introduced and the mechanism of the interaction of metal ions with DNA was discuss in detail.

Key words: DNA, conformation, transition
