Which organism has the highest percentage of adenine?

Yeast has the most important percentage of adenine with 31.3%, comparing to human which has 30.9% and other species like Streptococcus, Herring, and E.coli.

Generally, the percentage of adenine and thymine are equal, because they are linked together in the DNA, and the guanine and cytosine percentage are equal too. So if we have the percentage of adenine in the DNA of a species, we can figure out the other percentages.

Yeast is the organism with the highest percentage of Adenine. Adenine is a purine that is used in forming nucleotides of the nucleic acids. It has a variety of roles in biochemistry, in the form of energy-rich adenosine triphosphate and the cofactors nicotinamide adenine dinucleotide and flavin dinucleotide, and protein synthesis, as a component of DNA and RNA. It binds to thymine via two hydrogen bonds to help in stabilizing the nuclei acid structures.
