Okay kiddo, you know how every person is unique and different from others? Well, a knome is a company that helps people understand how unique they are by looking at their DNA.
DNA is like your body's instruction manual that tells it how to grow and function properly. Knome reads this code to understand what makes you special and different from everyone else.
They do this by collecting a tiny sample of your saliva or blood and then decoding it in their special laboratory. Once they have this information, they can tell you things like what diseases you may be more likely to get or what traits you may have inherited from your parents.
It's like a fun science project that helps you understand a lot about yourself!
