How does CRISPR gene editing technology work to treat diseases?

CRISPR is like a super-smart pair of scissors that can fix broken instructions inside our body to help us get better.

Imagine your body has a recipe book for making proteins, these are like the building blocks of life. Sometimes, the recipes have typos or mistakes, and that's when we get sick. CRISPR helps find those typos and correct them so the right proteins can be made again.

CRISPR has two main parts: guide RNA and Cas9, which is like a tiny pair of scissors.

1. The guide RNA is like a detective that finds the typo in the recipe book.
2. Once it finds the mistake, Cas9 cuts out the wrong part of the recipe so it can be replaced with the correct one.

This works just like when you're writing a letter and you find a spelling mistake, you cross it out and write the right word instead.

Think about someone who has sickle cell disease. Their blood cells are shaped like sickles because of a typo in their recipe book. CRISPR can go in and fix that typo, helping their blood cells return to normal shapes, making them feel better!

It’s like giving the body a spelling correction tool so it can write the right instructions again.
