Question

A human adult has approximately 37 trillion (3.7 x 1013) cells in their body. Each cell has roughly 6.5 picograms (6.5 x 10-12 grams) of DNA.
How much DNA (in grams) is in an adult human’s body? (Show your work)

Answer 1

240.5 gram DNA is in an adult human’s body.

Explanation:

DNA is the genetic material in human body. It is given that each human cell has approximately 6.5 picograms of DNA. It is also given that there are 37 trillion cells in the body.

We have to calculate the amount of DNA in human body.

Number of cells=37 trillion = $3.7 \times 10^1^3$    

Amount of DNA per cell= 6.5 picogram = $6.5 \times 10^-^1^2g$

Total amount of DNA in body= $3.7 \times 10^1^3 \times 6.5 \times 10^-^1^2$

=240.5 g
