2012 was a big year for the science of snipping DNA to introduce genetic changes into a cell, also known as genome editing. Though Science magazine hailed two new techniques for selectively cutting and pasting DNA in the field of genome engineering as together constituting one of the Top 10 scientific breakthroughs of the year, those methods may already have been surpassed by researchers at the University of California Berkeley using RNA and a single protein. Faster, simpler, and cheaper, the UCB team led by Dr. Jennifer Doudna published initial results of their work genetically modifying bacteria using the RNA-based DNA cleavage technique last summer. The response from the the life science community was extremely positive, with reviews calling it a "tour de force" and a "a real hit," according to the latest press release. Now three more papers are coming out based on the work of the Doudna Lab showing that the RNA programming technique using a bacterial enzyme known as Cas9 is equally effective in making alterations to human genes.
