Genetic engineering is when DNA is changed by people.
What's genetic engineering?

Come on! I can show you!
But what's DNA?




This is DNA. It is long strands of chemicals coiled together.
So things like hair and eye color are caused by DNA? That's so cool!
Welcome to DNA Town
It controls some of your traits. It is what makes you, you!
So what does genetic engineering do?


It can change some of these traits.
There are several steps to editing the DNA. It has gotten easier to do over time.


First, scientists make something to find the DNA that will be changed. It's like a little map.



Next, it is attached to something called the Cas9, which is like a pair of scissors.






Together, they travel to the section of the DNA that will be edited.


Here it is!
