Aretrotranspon known as line1 is about 1000 base pairs in length and is present in the human genome in about 516,000 copies. approximately what percentage of the human genome is accounted for by this transposon?
a. 0.0017%
b. 0.017%
c. 0.17%
d. 1.7%
e. 17%

17%

Explanation:

First, you need to know that the human genome have approximately 3,000 millions of base pairs, so if this retrotransposon is about 1,000 bp and have 516,000 copies, it will have 516,000,000 of base pairs in total. If you divide 516 millions by 3000 millions and then multiply it by 100, it will give you the percentage of the human genome accounted for this transposon.
