Xeno nucleic acid

Xeno nucleic acid (XNA) is a synthetic alternative to the natural nucleic acids DNA and RNA as information-storing biopolymers that differs in the sugar backbone.[1] As of 2011, at least six types of synthetic sugars have been shown to form nucleic acid backbones that can store and retrieve genetic information. Research is now being done to create synthetic polymerases to transform XNA. The study of its production and application has created a field known as xenobiology.

Although the genetic information is still stored in the four canonical base pairs (unlike other [2]

Structure

XNA exhibits a variety of structural chemical changes relative to its natural counterparts. Types of synthetic 'XNA' created so far include HNA, CeNA, TNA, GNA, LNA and PNA.[2]
