Scientists Just Added Four New Letters to the Genetic Code

A four-letter alphabet might seem limited, but it’s all nature needed to write the instructions for all life on the planet. News that researchers have added four letters to the genetic alphabet opens the door to new possibilities in synthetic biology, data storage, and even the search for life beyond our planet. The genetic code at the heart of all living things is elegantly simple. Each half of the famous double helix structure is built from four small molecules called bases: adenine, thymine, cytosine and guanine (ATCG).
