Beyond the natural nucleic acids DNA and RNA, nucleic acid chemistry has unlocked a whole universe of modifications to their canonical chemical structure, which can in various ways modify and enhance nucleic acid function and utility for applications in biotechnology and medicine. Unlike the natural modifications of tRNA and rRNA or the epigenetic modifications in mRNA and genomic DNA, these altered chemistries are not found in nature and therefore these molecules are referred to as xeno-nucleic acids (XNAs). In this review we aim to focus specifically on recent progress in a subsection of this vast field—synthetic genetics—concerned with encoded synthesis, reverse transcription, and evolution of XNAs. |
