Copyright © 2009 Pearson Education, Inc. DNA Fun Fact Length of DNA in human cell ~ 2 meters No. of cells in human body ~10 14 So, total length of DNA in human body ~ 2 x 10 14 meters = 2 x 10 11 km Distance from Earth to Sun ~ 1.5 x 10 8 km This means that you have enough DNA in your body to stretch back and forth between the Earth and Sun 1000 times!
