Question
Chapter 15.2, Problem 1C
Summary Introduction
To draw: A diagram showing a bacterial CRISPR locus and label each component within the locus.
Concept introduction: CRISPR or “clustered regularly interspaced short palindromic repeats” are short viral origin DNA repeats that are found in bacteria. Cas is CRISPR-associated endonucleases enzyme that excises the DNA. Therefore, CRISPR-Cas9 recognizes the invading virus and cleaves it. CRISPR-Cas9 system is used as a gene editing tool to genetically correct the disease causing mutations. This is used to edit the gene in the germ line of viable human embryos. These changes are heritable.
