glycol nucleic acid

Glycol nucleic acid (GNA)

Glycol nucleic acid (GNA) is a polymer similar to DNA or RNA but differing in the composition of its "backbone".

Threose nucleic acid (TNA) has also been proposed as a starting point, as has glycol nucleic acid (GNA), and like PNA, also lack experimental evidence for their respective abiogenesis.

Artificial nucleic acid analogs have been designed and synthesized by chemists, and include peptide nucleic acid, morpholino- and locked nucleic acid, as well as glycol nucleic acid and threose nucleic acid.
