In discovering how RNA works, American biochemist Marshall Nirenberg revealed how DNA directs the building of proteins and thus of life itself. And save the bees. A version of this story originally appeared in the June/July 2018 issue of Pacific Standard as a sidebar to "Deleting a Species." Recent advances in programmable nucleases, including the CRISPR-Cas9 system, mean that manipulating DNA has never been easier, which could fundamentally alter the way we treat and prevent human disease.

Copyright © 2020 Popular Science. (3) Epigenetics is able to shape the structure of the genome by tightly wrapping inactive genes to making them unreadable, and relaxing active genes to make them readable. Just because we have CRISPR doesn't necessarily mean we should use it. This modified Cas9, known as enzymatically dead Cas9 (dCas9), can be linked to one of several enzymes that change the epigenome, e.g., DNA demethylases, methylases, or acetyltransferases.

Shortly thereafter, Roundup-resistant weeds begin to appear in fields where those crops are grown. Genome editing with engineered nucleases, i.e. The $3-billion, 13-year project enabled scientists to read nature’s complete genetic blueprint for building a person. What are the stars up to? Scientists at the University of California– San Diego build the first gene drive in a lab-based population of fruit flies, and Imperial College London builds the first gene drive in lab mosquitoes. What made the moon, and what is it made of? Kayla Iacovino loves scaling active volcanoes as much as she loves modeling them in her NASA lab. Research on the bodies and behaviors of our furry (and creepy and crawly and slimy and slithery) cousins can help scientists learn more about our own species’ evolution and cognition. Herb Boyer and Stanley Cohen create the first genetically engineered organism—a bacteria with an added gene to confer antibiotic resistance—in Cohen's Stanford University lab.

By modifying the genomes of bacteriophages (bacteria-killing viruses) with CRISPR-Cas9 technology, scientists have been able to develop methods to destroy antibiotic-resistant bacteria. In cross-pollinating pea plants that produce either yellow or green pea seeds exclusively, he found the first offspring generation always had yellow seeds, but that the next generation had a 3.1 ratio of yellow to green.

In comparison, most gene-editing drugs operate on an ex vivo basis, where targeted cells are removed from the patient first before they are modified and later returned. Genome editing was pioneered in the 1990s, before the advent of the common current nuclease-based gene editing platforms, however, its use was limited by low efficiencies of editing.
