If a species has 35 percent adenine in its dna, what is the percentage of the other three bases?

The percentage of other bases are: Thymine = 35%, guanine = 15% and cytosine = 15%.

Explanation:

There are four bases in DNA molecules, the bases are adenine, thymine, guanine and cytosine. The quantity of adenine and thymine are always equal, so also, the quantity of guanine and cytosine are always equal. Based on the information given in the question, Adenine = 35%, this implies that thymine too is 35%. The two bases added together give 70% , leaving only 30% for guanine and cytosine. Cytosine and guanine will share this equally and so each one of them will have 15%.
