Complementary RNA A complementary RNA sequence that binds to a naturally occurring (sense) mRNA molecule, thus blocking its translation. The complementary RNA molecule is synthesized according to base-pairing rules, except that uracil is the complementary base to adenine.

Oligonucleotide analogues

The present invention relates to novel bicyclic and tricyclic nucleoside and nucleotide analogues as well as to oligonucleotides comprising such elements. The nucleotide analogues, LNAs (Locked Nucleoside Analogues), are able to provide valuable improvements to oligonucleotides with respect to affinity and specificity towards complementary RNA and DNA oligomers. The novel type of LNA modified oligonucleotides, as well as the LNAs as such, are useful in a wide range of diagnostic applications as well as therapeutic applications. Among these can be mentioned antisense applications, PCR applications, strand displacement oligomers, as substrates for nucleic acid polymerases, as nucleotide based drugs, etc. The present invention also relates to such applications.

The present invention relates to novel oligonucleotide chimera used as therapeutic agents to selectively prevent gene transcription and expression in a sequence-specific manner. In particular, this invention is directed to the selective inhibition of protein biosynthesis via antisense strategy using oligonucleotides constructed from arabinonucleotide or modified arabinonucleotide residues, flanking a series of deoxyribose nucleotide residues of variable length. Particularly this invention relates to the use of antisense oligonucleotides constructed from arabinonucleotide or modified arabinonucleotide residues, flanking a series of deoxyribose nucleotide residues of variable length, to hybridize to complementary RNA such as cellular messenger RNA, viral RNA, etc. More particularly this invention relates to the use of antisense oligonucleotides constructed from arabinonucleotide or modified arabinonucleotide residues, flanking a series of deoxyribose nucleotide residues of variable length, to hybridize to and induce cleavage of (via RNaseH activation) the complementary RNA.
