How does CRISPR gene editing work to cure diseases?

CRISPR is like a super precise pair of scissors that can fix broken parts inside our bodies.

Imagine your body is like a big book, and every page has instructions for how you grow and work, these are called genes. Sometimes, the pages get torn or have typos, which can cause diseases. CRISPR helps us find those mistakes and fix them.

How it works

CRISPR uses special tools to find the exact spot in the gene that needs fixing. It's like having a map to find your favorite toy in a messy room, you know exactly where it is!

Once it finds the mistake, it cuts out the wrong part of the gene. Then we can put in the right piece, just like replacing a broken lego with a new one.

Why it cures diseases

If we fix the wrong instructions in the body’s book, the body can start working better again, that’s how CRISPR helps cure diseases like sickle cell anemia or cystic fibrosis. It's not magic, just smart science!
