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.

Step-by-step 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 * 10^1^3`

Amount of DNA per cell= 6.5 picogram =
`6.5 * 10^-^1^2g`

Total amount of DNA in body=
`3.7 * 10^1^3 * 6.5 * 10^-^1^2`

=240.5 g
