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.
本文描述的是新型二价核碱基,它们在与
核酸或
核酸类似物骨架(遗传识别试剂或遗传识别试剂)结合时,可分别与匹配或不匹配的两条
核酸链结合。在一个实施方案中,
基因识别试剂是肽
