The genetic alphabet contains just four letters, referring to the four nucleotides, the biochemical building blocks that comprise all DNA. Scientists have long wondered whether it’s possible to add more letters to this alphabet by creating brand-new

A scientific breakthrough may finally allow scientists to create artificial DNA with new nucleotides that can create proteins.

For some theorists, the origin of life is defined as the natural origin of a self-replicating system capable of undergoing Darwinian evolution.
