title: Characterization of four-stranded DNA and RNA fragments.
abstract: We have investigated the structures formed by deoxyribo- and ribooligonucleotides containing guanine-rich sequences. Inter- and intrastrand guanine tetrads are not only more stable in the presence of K+ than they are in the presence of Na+, but also more compact.
