Describe your reasoning. As guanine and cytosine are complementary, another 15% of the nucleotides must have cytosine. The remaining 70% of the nucleotides (100%-30%) must have adenine and thymine in equal proportions (35% each), as they are complementary to each other.f 15% of the nucleotides in a DNA molecule contain guanine, what percentage of the nucleotides having each of the other three bases?
What are the three parts of a DNA nucleotide, and how are they connected to each other? 2. If 15% of the nucleotides in a DNA molecule contain guanine, what percentage of the nucleotides contain each of the other three bases? Explain your reasoning. 3. Why is complementary base pairing important in DNA structure? 4. Critical Thinking How did X-ray diffraction photographs help Watson and Crick determine the structure of DNA?
