A composition includes a polymer including extending chains, side chains, or branches. One (or more) of a plurality of a first strand of nucleic acid is attached to each of a plurality of the side chains. One (or more) of a plurality of a second strand of nucleic acid, which is complementary to the first strand of nucleic acid, is complexed to each of the plurality of the first strand of nucleic acid to form a double strand of nucleic acid on each of the plurality of the side chains. At least one fluorescent compound is associated with the double strand of nucleic acid on each of the plurality of the side chains.

Nucleic acid-polymer conjugates for bright fluorescent tags

A method of synthesizing a polynucleotide composition includes attaching a compound including at least one initiator or at least one transfer agent for a reversible deactivation radical polymerization to an end of a nucleotide chain assembly immobilized upon a solid phase support during a solid phase synthesis of a polynucleotide so that the initiator or the transfer agent is attacked to the end of a nucleotide chain assembly in a manner which is stable under conditions of deprotection of the polynucleotide, and growing a polymer from the initiator of from a site of the chain transfer agent via the reversible deactivation radical polymerization to form the polynucleotide composition.

Functionalized polymer hybrids

Provided herein are compositions for the modification of gene expression by RNA interference using a microRNA (miRNA) guide strand precursor. Methods of making and using the miRNA guide strand precursor also are provided. The compositions bypass the Drosha-Exportin-Dicer pathway and are resistant to nucleases.
