title: The conformation and stability of ribonucleic acids: modeling base sequence effects in double stranded helices.
abstract: Base sequence effects within double stranded RNA oligomers of A and Z conformations have been studied by molecular modeling using a methodological approach specifically adapted to nucleic acids. Calculations on symmetric oligomers having homonucleotide or dinucleotide repeating base sequences show that sequence changes can produce modifications in overall conformation, influence the degree of internal hydrogen bonding and strongly affect stability.
