Described herein are divalent nucleobases that each binds two nucleic acid strands, matched or mismatched when incorporated into a nucleic acid or nucleic acid analog backbone, such as in a γ-peptide nucleic acid (γPNA). Also provided are genetic recognition reagents comprising one or more of the divalent nucleobases and a nucleic acid or nucleic acid analog backbone, such as a γPNA backbone. Uses for the divalent nucleobases and monomers and genetic recognition reagents containing the divalent nucleobases also are provided.
本文描述了二价核碱基,每个核碱基在纳入到核酸或
核酸类似物骨架中时能够与两条核酸链结合,无论是匹配还是不匹配,例如在γ-肽核酸(γ
PNA)中。还提供了包含一个或多个二价核碱基和核酸或
核酸类似物骨架(如γ
PNA骨架)的遗传识别试剂。此外,还提供了包含二价核碱基的二聚核碱基和单体以及遗传识别试剂的用途。
