If a molecule of DNA is made up of 40% Adenine, what percentage is Thymine?
|
20%
|
|
40%
|
|
10%
|
|
80%

Explanation:
Detailed explanation-1: -Therefore, Guanine would be 20% and total of G+C = 40% and hence A+T would be 60% that is 30% each. Hence, option C is correct answer.
Detailed explanation-2: -According to Chargaff’s rule, Concentration of adenine=concentration of thymine. therefore if [A]=40% then the [T] will also be 40%.
Detailed explanation-3: -Answer: There would be 20% Cytosine.
Detailed explanation-4: -The final composition is 22% adenine, 22% thymine, 28% cytosine, and 28% guanine. Uracil is only found in RNA.
