DNA helix encoding all the proteins in our body
DNA helix encoding all the proteins in our body
Our genetic information is coded on our DNA by four naturally occurring bases that together specify the 20 amino acids that make up the proteins of our body. Now biochemists have added two more foreign chemical bases to the DNA code, and show that they work together with the natural bases to make functional proteins in bacteria. This is an important step in synthetic biology, and might lead to the generation of completely new proteins that can be used in the treatment of diseases or solve antibiotic resistance.
