Both proximal and long-range regulatory features are more highly conserved between species by evolutionary selective pressure than is the surrounding non-regulatory DNA.
To further assess whether GC-D is functional in lemur and bushbaby we examined evolutionary selective pressures by estimating rates of synonymous and nonsynonymous substitutions.
Evolutionary selective pressures have tuned the efficiency of the protein‐folding reaction in the crowded complex environment in the cell.
blaTEM-135 does not appear, as previously hypothesized, to have recently evolved due to, for example, some evolutionary selective pressure by the extended-spectrum cephalosporins.
blaTEM-135 does not appear, as previously hypothesized, to have recently evolved due to some evolutionary selective pressure, for example, by the extensive use of extended-spectrum cephalosporins worldwide.
This idea is further strengthened by the fact that some CGs have endured purifying evolutionary selective pressure and are conserved in other vertebrate genomes such as chimpanzee, macaque, mouse, and dog.
And Ebola expert Dr. Thomas Geisbert explains that while the risk for Ebola to accumulate a series of mutations that would allow it to spread by air is "probably not zero," there is, in fact, no evolutionary selective pressure on it to do so.
Cordain, L. & Hickey, M. S. Ultraviolet radiation represents an evolutionary selective pressure for the south-to-north gradient of the MTHFR 677TT genotype.
