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?
There are intron identifying portions: The 5' splice site, consisting of a guanine next to a uracil base at the 5' end of the intron. The 3' splice site, consisting of an adenine next to a guanine at the 3' end of an intron. The branch point A, located about 30 nucleotides from the 3' end, consisting of just one adenine.
