What are gene editing technologies?

Gene editing technologies are tools that let scientists change parts of our DNA, just like fixing a typo in a story.

Imagine you're writing a letter, and you accidentally write "go to the park" instead of "go to the lake." You might cross out "park" and write "lake" above it. That's kind of what gene editing does, it lets scientists find a mistake or a part they want to change in our DNA and fix it.

Like Fixing a Book

Think of your DNA as a very long book that tells your body how to work. Sometimes there are spelling mistakes in the book, which can make your body do strange things. Gene editing is like having a special pencil that lets you correct those spelling mistakes, one letter at a time.

Like Changing a Recipe

Sometimes scientists want to add something new or take something out of the DNA book, just like changing a recipe. They use different tools for this, like CRISPR, which acts like a pair of scissors that can cut out a part of the story so it can be replaced with something else.

It’s not magic, it's science made simple!
