The purpose of the call was to interest Doudna in studying an emerging phenomenon that was recently discovered in microbiology, a strange sequence of DNA found in bacteria. Intrigued, Doudna began to research the sequences, called Crispr, in her own lab and, in 2012, discovered that they could be used as a powerful new tool for editing genes. Today, Crispr is creating a revolution in genomics, completely redefining what was considered to be possible in just a few short years.
