Your DNA could stretch from the earth to the sun and back ~600 times. If unwound and linked together, the strands of DNA in each of your cells would be 6 feet long. With 100 trillion cells in your body, that means if all your DNA were put end-to-end, it would stretch over 110 billion miles. That’s hundreds of round trips to the sun!
Your DNA could link you to places you’d never imagine. Genetics has the power to tell you things you never dreamed of knowing, from just the DNA in your saliva. With an AncestryDNA test, for example, you can find out which world regions your ancestors may have lived in hundreds to thousands of years ago, what bonded them over generations, and why and where they migrated – all from your DNA.
