INTERESTING FACTS ABOUT DNA!!!!!
1. 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!
2. Of the 3 billion base pairs in the human genome, only 0.1% are unique to us. While that 0.1% is still what makes us unique, it means we’re all more similar than we are different.
3. Genes are short segments of DNA, but not all DNA is genes. All told, genes are only about 1-3% of your DNA. The rest of your DNA controls the activity of your genes.
4. Your sister could be much more Irish than you. And this is true for any of over 350 regions covered by the AncestryDNA test. So your sibling could also be more (or less) British, Nigerian, or Scandinavian than you.
5. DNA molecules are shaped like twisted ladders. And the rungs on that ladder are made of bases – adenine (A), cytosine (C), guanine (G), and thymine (T) – locked together in pairs with hydrogen bonds. The really cool part is, they pair up in a very specific way: ‘A’ always pairs with ‘T,’ and ‘C’ always pairs with ‘G.’
6. 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.
