If a DNA molecule has 24% adenine, what is the percentage of guanine in the same DNA molecule?
artcher [175]

Answer:

26%

Explanation:

Adenine pairs with thymine.

Guanine pairs with cytosine.

If 24% of the DNA molecule is adenine, that means that there is 24% thymine. This is because they pair together so they have to be equal. That is 48% of the DNA molecule. To find the percentage of guanine, we need to minus 48% from the total 100%.

100 - 48 = 52

Then divide by 2 because you have guanine AND cytosine.

52/2 = 26

Therefore, your final answer is 26% of guanine is in the DNA molecule.

<em>I hope this helps!!</em>
