And what we did is, in order to figure all this out, sort of trace the path of evolution, we did a whole bunch of sort of, swapping experiments, where we swappedGAL1 for GAL3and we swapped the ancestral protein type of protein in for GAL1or for GAL3, and we even swapped the GAL1and GAL3in for the ancestral protein, in another yeast that didn't have the duplication take place; and from this whole series of experiments, we really expected to find out pretty much how the proteins have changed; and the surprise was that most of [the] adaptive change that had taken place wasn't in the protein, it was in how the two genes were regulated.

So, I'll just say a little more about why yeast; which is, over the decades, yeast molecular biologists have devised so many powerful tools that allow you to make very precise changes in yeast, in their DNA; exquisite control, where you can change a single base that you want in a particular place, you can put a whole gene in, take a whole gene out, swap genes etc..

«The other thing I think is interesting is that there are not that many cases where people have been able to use gene expression, absent any genetics, to zoom in so precisely on a genetic change that causes an obvious trait,» he added.

One of the mechanisms driving alterations in gene expression is epigenetic change, where the female is able to change her offspring's genome to cause certain genes to be expressed differently.

It is tempting to speculate that these mutations destroy or change gene regulatory functions, altering when and where genes turn on.

Instead, the disease - linked genetic changes appear to occur in vast tracts of sequence between genes where ENCODE has identified many regulatory sites.

To understand the genetic causes of disease, we need to know which genes are involved in development, as well as when and where they act and how this changes with time.
