GENEius FACTS

1 . There are 37.2 trillion cells in the human body . If unwound and tied together , the strands of DNA in one cell would stretch to nearly six feet . Amazingly , if all the DNA in your body was arranged end to end , it would reach the sun and back close to 230 times ! Or a return trip to Pluto !
2 . We are more alike than different ! The genetic similarity between humans is 99.9 %. Only 0.1 % of our DNA is responsible for the vast variety of physical traits that makes us different from each other . But the differing 0.1 % equates to 3 million differences in DNA .
