Abstract
The base pairing of a series of homooligomeric or telomeric oligonucleotides built-up from 2′-deoxy-β]-D-xyloadenosine and/or -thymidine were synthesized and studied with respect to their thermodynamics of duplex formation. Oligo (2′-deoxyxylonucleotides) are more stable than the corresponding regular oligomers the more d(xA-xT) elements they contain.
