diego CRISPR Gene Editing
Wake up the silent gene (wake up!) / Fetal blood runs healthy and clean (so clean!)

diego CRISPR can be injected directly into the eye to repair genetic mutations that cause inherited blindness.

diego Scientists are using CRISPR to locate and destroy viral DNA that hides inside human cells, including HIV.
Fun Fact
Fetal hemoglobin trick: The drug Casgevy cures sickle cell by turning back on a gene we only use as babies.
Glossary
crispr (noun)
A genetic engineering tool used to make precise, targeted changes to the DNA of a living organism. In 2019, clinicians first used this molecular tool to treat Victoria Gray's hereditary sickle cell disease.
