Demystifying Medicine Video

This video describes the novel gene-editing process known as prime editing. Prime editing is based on the CRISPR/Cas9 mechanism of gene editing. Prime editing is aimed to be a more precise version of gene editing through the use of reverse transcriptase and prime editors, thereby reducing off-target effects that can cause mutations. The video looks at the public's perspective on gene editing as well as suggested ethical solutions from recent literature.

For more information on CRISPR/Cas9 and how it works, please view this video on the McMaster Demystifying Medicine channel: What is CRISPR? And how does it work?
