title: Highly selective binding of metal ions to thymine-thymine and cytosine-cytosine base pairs in DNA duplexes.
abstract: Very specific binding of of Hg(II) and Ag(I) cations unexpectedly and significantly stabilizes the naturally occurring miss-base pairs, thymine-thymine and cytosine-cytosine, in DNA duplexes.
