The expanding world of DNA and RNA.

The expanding world of DNA and RNA. Curr Opin Chem Biol. 2016 Aug 23;34:80-87 Authors: Chen T, Hongdilokkul N, Liu Z, Thirunavukarasu D, Romesberg FE Abstract DNA and RNA are remarkable because they can both encode information and possess desired properties, including the ability to bind specific targets or catalyze specific reactions. Nucleotide modifications that do not interfere with enzymatic synthesis are now being used to bestow DNA or RNA with properties that further increase their utility, including phosphate and sugar modifications that increase nuclease resistance, nucleobase modifications that increase the range of activities possible, and even whole nucleobase replacement that results in selective pairing and the creation of unnatural base pairs that increase the information content. These modifications are increasingly being applied both in vitro and in vivo, including in efforts to create semi-synthetic organisms with altered or expanded genetic alphabets.
