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?
If 50% comes from each parent, then they should, in theory have 50% from the common parent. I know this is not so, but I do not know why. -A curious adult from Peru. These percentage things are always tricky. While we do get 50% of our DNA from each parent, we donât get the same 50% as our siblings. In general, there is about a 50% overlap between the DNA you got from your mom and the DNA your brother or sister got from that same mom. So you and your sibling share 50% of 50% of momâs DNA or 25%. I always find this kind of explanation to be a bit confusing. An easier way to see what is going on is to do a simple experiment with a deck of cards.
