'Junk DNA' defines differences between humans and chimps
For years, scientists believed the vast phenotypic differences between humans and chimpanzees would be easily explained – the two species must have significantly different genetic makeups. However, when ...

Although our genetics differ significantly, we all look alike
The genetic variation within a species can be significant, but very little of that variation results in clear differences in morphology or other phenotypes. Much of the diversity remains hidden ‘under the surface’ in buffered ...

Prion proteins play powerful role in survival, evolution of wild yeast strains
Prions, the much-maligned proteins most commonly known for causing "mad cow" disease, are commonly used in yeast to produce beneficial traits in the wild. Moreover, such traits can be passed on to subsequent generations and ...

Noncoding RNAs alter yeast phenotypes in a site-specific manner
Personal change can redefine or even save your life—especially if you are one of a hundred yeast cell clones clinging to the skin of a grape that falls from a sun-drenched vine into a stagnant puddle below. By altering ...
