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.
                            一种合成多核苷酸组合物的方法包括将至少一种包括至少一个
引发剂或至少一个可逆去活基团聚合转移剂的化合物连接到固相合成多核苷酸过程中固相支持物上固定的核苷酸链组装的末端,以使
引发剂或转移剂被连接到核苷酸链组装的末端,其在多核苷酸去保护条件下是稳定的,并通过可逆去活基团聚合从
引发剂或链转移剂的位置生长聚合物,形成多核苷酸组合物。
