Cool. Simulated yeast.
As the yeast genome has been sequenced, Palsson and his colleagues have examined each gene, to understand how it functions. We typically think of genes making proteins and leave it at that, but actually many of these proteins turn around and influence the production of other proteins. In some cases, genes can't make their proteins at all unless another protein switches them on. In other cases, proteins can shut down the pathway that allows a protein to be made. This allows organisms to be more than just biological factories, blindly cranking out proteins. Instead, they produce proteins only as needed, in response to changes in the environment for example, or in order to take the next step in their life cycle. Genes are a lot like electrical components this way, wired together into metabolic circuits. [The Loom]
I can't wait to see where this goes over the next decade.
