Artificial nucleosides including 2-methyl-nucleobase-substituted butane-1,3-diol nucleosides are disclosed. Four different stereoisomers of such nucleosides are possible. Oligonucleotides made up of the artificial nucleosides form homoduplexes of greater stability than DNA duplexes and have a reduced ability to hybridize to DNA or RNA.
