Artificial DNA Expands Definition Of Life On Earth, Synthorx Reveals

Well, there’s no way this could go wrong.

According to recent announcements, a small biotech startup in California has successfully added new synthetic components to the genetic alphabet of DNA, potentially creating entirely new kinds of life on Earth.

You’d need a Ph.D. or three to really get into it, but here goes: DNA, the organic molecule that carries genetic information for life, is made from a limited chemical “alphabet.” DNA can be thought of as a molecular code containing exactly four nitrogen-containing nucleobases — cytosine (C), guanine (G), adenine (A), or thymine (T). All known living organisms on the planet, from bacteria to biologists, are based on combinations of this four-letter molecular code: C-G-A-T.
