The binding mode of (en ס ם3 Co(en) 3 ethylenediamine) to calf thymus DNA is investigated using electrochemical and spectroscopic methods. Binding constant value (K ס 1.284 ן 10 3 L/mol) is found to be the same by the two methods. Both isomers show the same CV behavior associated with bindin
## Abstract The interaction of the La(III) and Tb(III) ions with adenosine‐5′‐monophosphate (5′‐AMP), guanosine‐5′‐monophosphate (5′‐GMP), and 2′‐deoxyguanosine‐5′‐monophosphate (5′‐dGMP) anions with metal/nucleotide ratios of 1 and 2 has been studied in aqueous solution in acidic and neutral pHs.
