Question:
If 20% of the nucleotides in a DNA molecule are adenine, what percentage of each of the other three bases would be found in this molecule? Explain your answer. This is known as?

If 20% of the nucleotides in a DNA molecule are adenine, according to Chargaff's rules, the complementary base-pairing in DNA dictates that the percentage of thymine (T) will also be 20%. Similarly, since adenine pairs with thymine, the percentages of cytosine (C) and guanine (G) will be equal. Therefore, both cytosine (C) and guanine (G) would each make up 30% of the nucleotides. This principle is known as Chargaff's rules, which state that in a DNA molecule, the amount of adenine is equal to the amount of thymine, and the amount of cytosine is equal to the amount of guanine.
