The Secret Behind CRISPR Gene Editing

Send us a Text Message.

Humans have ~6 billion bases of DNA in each cell. But every gene has a specific and unique sequence that serves as a kind of genetic address. Before any gene can be edited, the editor must first find the gene's location within the genome. Luckily CRISPR-Cas has a built-in GPS component that makes finding a gene address easy, and switching out one genetic address for another is as easy as typing a street address into your Google Maps navigation app...well almost as easy.

In this episode, show hosts Fatu and Shekerah deliver the second installment of the CRISPR Chronicles series.  We discuss the secret sauce that makes CRISPR-Cas gene editing powerful, flexible, and easy to use—it's the gene editing genie that the scientific community had been waiting for.  CRISPR-Cas gene editing has two main components (RNA and protein), each of which plays a critical role. The merger of these 2 components into a unified system is what makes CRISPR-Cas gene editing superior to its predecessors.
 
Zinc Finger Nucleases (ZFNs) and TAL Effector Nucleases (TALENs) were the gene editing tools of choice before CRISPR-Cas9 was discovered. Unfortunately, the design, production, and implementation of ZFNs and TALENs were difficult and expensive, which prevented their rapid adoption on a global scale as has occurred with CRISPR-Cas9 gene editing.
