Question

Sense of Proportion: The DNA in a single cell in your body contains about 4.5 billion base pairs. Imagine building a model of that DNA like a ladder with base pairs for rungs. If you make the rungs 1 inch apart, how long will the ladder be

Answer 1

Calculate the distance between
`4.5* 10^(9)` two consecutive rungs.

D= (
`4.5* 10^(9)`-1) inch= 4

Step-by-step explanation:

The number of base pairs are 4.5 billion = ,

So, the number of rungs with base pairs are ,

The distance between two rungs is 1 inch.

Calculation '

Calculate the distance between consecutive rungs.

D= ( -1) inch= 4
