      There’s a strand of DNA inside your cells – if this was stretched out, it would be about 3 meters long – about as tall as a double-decker bus!

      Since we have about 10 trillion cells, we have 10 trillion DNA molecules. If these were stretched out end to end, they would cover the distance between the Earth and the Sun 100 times over!
