The interaction of Mg2+, Ca2+, Zn2+, and Cd2' with calf thymus DNA has been investigated by Raman spectroscopy. These spectra reveal that all of these ions, and particularly Zn2+, bind to phosphate groups of DNA, causing a slight structural change in the polynucleotide at very small metal : D N A (
