A University of Oregon research team has tried, in essence, to return a protein — called a glucocorticoid receptor — to one of its ancestral states by reversing the mutations that produced the modern version of the receptor.
The mutations that met the criterion for rarity were excluded from the list.
The third change involves mutations that alter the inner contents of the microbe, so that the antibiotic can no longer inactivate its target.
The simian primate lineage might have acquired mutations that stabilize the interface, whereas the murine lineage might have accrued mutations that destabilize the interface.
The mutations that exert the greatest effect in causing tumour formation are referred to as driver mutations.
The mutations that encode the determinants for differential crow virulence are currently unknown.
Then the mutations that had the largest positive effects on resistance to ionizing radiation were combined.
Fouchier was unable to confirm the specific mutations that made the virus more transmissible, but said many had already been spotted in the wild.
One can also find the single mutations that caused the largest smoothing.
The point mutations that activate the PIK3CA have been observed in some gliomas [ 18].
Right now they're using mice that have genetic mutations that make the proteins inaccessible to the bacteria.
