Abstract:
[structure in text] The synthesis of (2S,4S)- and (2R,4S)-aepPNA monomers of adenine, guanine, and cytosine (3-5) and their incorporation at appropriate positions into aegPNA sequence 7 leads to mixed aeg-aep backbone/mixed nucleobase PNAs 8-11. The thermal stabilities of the derived duplexes with DNA are found to be dependent on nucleobase and backbone stereochemistry.

DNA and RNA
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria. In prokaryotes, the...
