Peptide nucleic acid (PNA) forms a triple helix with double-stranded RNA (dsRNA) stabilized by a hydrogen-bonding zipper formed by PNA's backbone amides (N-H) interacting with RNA phosphate oxygens. This hydrogen-bonding pattern is enabled by the matching ∼5.7 Å spacing (typical for A-form dsRNA) between PNA's backbone … WebBackground. When choosing what plasmid backbone to use, you have many elements to consider. Here is a guide to Addgene's empty vector backbones.
