Lecture on gene editing with CRISPR-Cas scissors.

A lecture about CRISPR-Cas, the so-called genetic scissors that allow DNA to be modified in a targeted way. The molecular tool has led biology into a new era of targeted gene editing. The talk explains how it works and how it is changing processes in medicine, agriculture and research. It also addresses the possibilities of deliberately influencing biological systems and the ethical boundaries between intervention, optimisation and redesign.
