A simple and accessible CRISPR genome editing laboratory exercise using yeast.

CRISPR is a revolutionary tool to engineer the genome. Herein, we describe a laboratory exercise designed to introduce students to CRISPR by editing the genome of yeast to disrupt the gene, which results in yeast that form red colored colonies. The experiment was constructed to be performed in a single laboratory session and to be accessible to students and instructors without experience working with yeast.
