A novel class of compounds, known as peptide nucleic acids, bind complementary ssDNA and RNA strands more strongly than a corresponding DNA. The peptide nucleic acids generally comprise ligands such as naturally occurring DNA bases attached to a peptide backbone through a suitable linker.
一类被称为肽核酸的新型化合物能比相应的 DNA 更强地结合互补的 ssDNA 和 RNA 链。肽核酸一般由
配体组成,如通过合适的连接体连接到肽骨架上的天然 DNA 碱基。
