Question
e number of cells in an average-sized adult human is on the order of 10A14 cells. Use this information, and the estimate that the length of DNA contained in each cell is 2 meters, to do the following calculations. Show all of your work with units. Some conversions that might be useful: 1 meter-6.21 X 10A-4 miles Average Distance from Earth to the Sun=93,000,000 miles= 9.3 X 1017 miles A. Over how many miles would the total DNA from the average human stretch? B. How many times would the total DNA from the average human stretch from Earth to the Sun and back?Explanation / Answer
Given:
Calculate :
1. The average human DNA will stretch how many miles?
2. How many times would the DNA stretch from earth to the sun and back?
The Total DNA length of the human body is 2 x 10 14 meters.
The number of miles that the total DNA stretches is 2 x 10 14 * 6.21 x 10-4 miles=12.42 x 1010 miles.
The number of times the DNA would stretch to the sun and back=12.42 x 1010 miles/ 9.3 x 107 miles= 1.335 x 103 miles.
