Described herein are novel divalent nucleobases that each bind two nucleic acid strands, matched or mismatched when incorporated into a nucleic acid or nucleic acid analog backbone (a genetic recognition reagent, or genetic recognition reagent). In one embodiment, the genetic recognition reagent is a peptide nucleic acid (PNA) or gamma PNA (?PNA) oligomer. Uses of the divalent nucleobases and monomers and genetic recognition reagents containing the divalent nucleobases also are provided.
本文描述了一种新颖的二价核碱基,每个核碱基可以结合两条核酸链,无论是匹配还是不匹配,当它们被合并到核酸或
核酸类似物的骨架中(一种遗传识别试剂,或遗传识别试剂)。在一个实施例中,遗传识别试剂是肽核酸(
PNA)或γ
PNA(?
PNA)寡聚体。还提供了含有二价核碱基的单体和遗传识别试剂的用途。
