CRISPR-Cas systems are prokaryotic immune systems that confer resistance to foreign genetic elements such as plasmids and phages. CRISPR-Cas systems have been exploited for targeted genome editing.

Both tourists and locals favor Cas Abao Beach, and it's not difficult to see why. The white-sand beach is surrounded by cliffs and lush greenery, and shaded by thatched palapas (large palm umbrellas).

CRISPR-Cas9 genome editing exploits the CRISPR-Cas system to modify a genome in a targeted manner. Guided by RNA, the Cas9 endonuclease breaks DNA at a target sequence. Imprecise repair of the double ...
