The distance between base pairs in DNA is 0.34 nm.How many base pairs are there in a chromosome that is 12.0 cm long? (Note: 10⁹ nm = 1 m)

Question

Quizplus · Accepted Answer

First, we need to convert the length of the chromosome from centimeters to meters:

12.0 cm = 0.12 m

Next, we need to divide the length of the chromosome by the distance between base pairs:

0.12 m / 0.34 nm = 3.529 x 10^8

Finally, we need to convert the answer from nanometers to base pairs:

3.529 x 10^8 base pairs = 3.5 x 10^8 base pairs

Therefore, the best answer is C, which is 3.5 x 10^8 base pairs.

The Distance Between Base Pairs in DNA Is 0
