Article: Royal Society of Chemistry: Expanded genetic alphabet could spell out new genes

“Chemists have created an artificial genetic code capable of evolving to produce new genes. The code consists of six bases, rather than the standard four, and could form the basis of randomly mutating synthetic life. Steven Benner, at the Foundation for Applied Molecular Evolution, US, credited as the man who kick-started the field of 'synthetic biology', is behind the work. Benner created two new molecules which can be slotted into DNA alongside regular adenine (A), thymine (T), cytosine (C) and guanine (G) bases. The new bases, dubbed 'P' and 'Z,' look similar to natural ones but have orthogonal hydrogen bonding patterns”
