title: Condensation reaction of hexanucleotides containing guanine and cytosine with water soluble carbodiimide.
abstract: The condensation reactions of hexanucleotides involving guanine and cytosine in the presence of water-soluble carbodiimide (WSC) have been investigated as a model reaction of the prebiotic formation of RNA under primitive earth. The reactions formed cyclic hexanucleotides and dimers in which the product yields were dependent on the sequence.
