If 15 percent of the nitrogenous base in a sample of DNA is thymine what percentage should be cytosine?

35% if 15% is thymine, 15% must adenine therefore 70% is cytosine and guanine divided by 2 = 35% cytosine.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
