Explicación sencilla
Emmanuelle Charpentier studies how bacteria work. She discovered a small RNA molecule — tracrRNA — that turned out to be an essential part of how the CRISPR system functions, a piece nobody knew was needed. That discovery made the collaboration with Jennifer Doudna possible, and the two showed together that the system could be programmed.
Profundizar
Emmanuelle Charpentier is founding and scientific director of the Max Planck Unit for the Science of Pathogens in Berlin. Her 2011 identification of trans-activating CRISPR RNA in Streptococcus pyogenes revealed a required component of type II CRISPR function; the subsequent collaboration with Doudna produced the 2012 demonstration of programmable Cas9 cleavage. She co-founded CRISPR Therapeutics, which went on to develop the first approved CRISPR medicine.
