Final answer:
According to Chargaff's rule, DNA contains equal amounts of adenine (A) and thymine (T), while uracil (U) is not present in DNA. Hence, if DNA has 36% adenine, it also has 36% thymine, and 0% uracil.
Step-by-step explanation:
If DNA contains 36% adenine (A), then according to Chargaff's rule, which states that DNA is composed of base pairs where adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G), there would also be 36% thymine (T) in the DNA. Uracil (U) is not found in DNA, but rather in RNA, where it takes the place of thymine. Therefore, the percentage of uracil in DNA is 0%.
