Imagine your DNA is a giant instruction book for your body. Sometimes a word in that book gets spelled wrong. CRISPR is like a super-smart pair of scissors and a tiny GPS. It finds the exact wrong word and cuts it out. Then the body fixes the sentence. This helps doctors treat sick people by fixing their genes. It works because the tool knows exactly where to go in the huge book.
Examples
- Fixing a typo in a long storybook so the meaning is correct.
- Using a highlighter to find one word in a huge encyclopedia.
- Replacing a broken lightbulb with a new one instantly.
