Extra letters added to DNA

[Jubal]

Sharing this because it's super interesting:

Scientists have created bacteria that thrive using an expanded "genetic alphabet".
The blueprint for all life forms on Earth is written in a code consisting of four "letters": A, T, C and G, which pair up in the DNA double helix.
But the lab organism has been modified to use an additional two, giving it a genetic code of six letters.
Researchers hope the work could lead to bugs that can help manufacture new classes of drugs to treat disease.
