  1. CRISPR gene editing (pronounced / ˈkrɪspər / "crisper") standing for "Clustered Regularly Interspaced Short Palindromic Repeats" is a genetic engineering technique in molecular biology by which the genomes of living organisms may be modified. It is based on a simplified version of the bacterial CRISPR - Cas9 antiviral defense system.

    Before we jump into CRISPR, let’s start with the concept of gene editing. Gene editing is the process of altering genetic material (DNA). That could mean changing a few individual genes or an entire sequence. Research has been ongoing for more than a decade that’s looking at using gene editing on mutations that cause serious health conditions in pe...

    Now that we’re clear on what gene editing is, let’s focus on a specific approach: CRISPR. Clustered Regularly Interspaced Short Palindromic Repeats, otherwise known as CRISPR, “was originally identified in bacteria, as a bacterial defense system,” says Dr. Chan. That’s right. Bacteria have immune systems, too. CRISPR contains “spacers” — sequences ...

    You can think of the underlying mechanism of CRISPR gene editing as being similar to the way magnetic shapes are drawn to each other or the way Lego blocks fit together. The segments in CRISPR are transcribed into RNA. This RNA includes a guide sequence, which is a match to existing DNA in a person’s body. “That guide sequence can be tailored to wh...
