There is enough DNA in an average person’s body to stretch from the sun to Pluto and back — 17 times!
Science Fun Fact #1
The human genome, the genetic code in each human cell, contains 23 DNA molecules each containing from 500 thousand to 2.5 million nucleotide pairs.
There are about 37 trillion cells in the human body, you read that right 37 TRILLION CELLS!
If you uncoil the entire DNA encased in each cell and put them end to end, then these would sum to a total length of 2×1014 meters or enough for 17 Pluto roundtrips (1.2×1013 meters/Pluto round trip).
