Length of a Human DNA Molecule

Length of a Human DNA Molecule:

1 cromossomo ___ ~5cm
1 célula _____ ~2.5m


(length of 1 bp)(number of bp per cell)(number of cells in the body)
(0.34 × 10-9 m)(6 × 109)(1013)
2.0 × 1013 meters

That is the equivalent of nearly 70 trips from the earth to the sun and back.
2.0 × 1013 meters = 133.691627 astronomical units
133.691627 / 2 = 66.8458135 round trips to the sun
