The genetic code is the recipe for life, and provides the instructions for how to make proteins, generally using just 20 ...
Scientist suggests viewing genetic code not as a static "manual" that determines how organisms function, but a dynamic process of the birth of meaning and signs—semiosis. As part of this approach, the ...
