CRISPR functions as a prokaryotic immune system and provides resistance to exogenous genetic elements such as plasmids and phages in the form of acquired immunity. Whereas, Short segments of foreign DNA, called spacers, are incorporated into the genome between CRISPR repeats, and serve as a 'memory' of past exposures; which are then used to recognize and silence exogenous genetic elements.

Is it possible to have a revolution in medical sciences concerning such adaptive modifications and functional uniformity among organisms. Can we start a broad discussion with this new discovery.
