Semi-synthetic DNA expands genetic code with two new bases
Scientists at The Scripps Research Institute unveil a bacterium containing two artificial DNA bases X and Y. The organism reads and translates these bases into RNA and proteins, potentially enabling drugs and materials with up to 152 amino acids. Lead researcher Floyd Romesberg notes it as a major step toward alternative life forms, though the organism requires lab conditions to survive. Synthorx, Romesberg’s startup, aims to harness these bases to design novel proteins for therapies.
