UNIVERISTY PARK, Pa. — The tumor suppressor protein p53, known as "the guardian of the genome," protects the body’s DNA from daily stress or long-term damage by triggering the cells to make repairs or ...

Gene editing is one of the latest breakthroughs in biology. The widely known CRISPR-Cas gene editing system provided prokaryotes (organisms that lack cell nuclei) an immunity against foreign DNA.

Scientists look at the base pairs that compose the "rungs" of the DNA ladder to determine a genome's sequence. The success of E. coli bacteria depends on their ability to multiply very rapidly by ...

In the early 1980s, David Gilmour, now an emeritus biochemistry and molecular biology professor at Pennsylvania State University, joined the laboratory of geneticist and biochemist John Lis as a ...

DNA-nanoparticle motors are exactly as they sound: tiny artificial motors that use the structures of DNA and RNA to propel motion by enzymatic RNA degradation. Essentially, chemical energy is ...

In Lewis Carroll's "Through the Looking-Glass," Alice is stuck in a never-ending race with the Red Queen yet never gains a ...
