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).
