Summary
How can new genes evolve? It was long thought that this happens only through duplication and recombination of existing genes. An experimental evolution approach now shows that a large fraction of randomly composed protein sequences can positively or negatively influence the growth of cells. These results indicate how new genes can also arise out of non-coding sequences of the genome. Concurrently, this opens a practically unlimited source of new bioactive molecules for pharmacological and biotechnological applications.
