Question

A forensic scientist is trying to find out the number of adenine in the DNA sample that he obtained from a crime scene.

What can he assume about the number of adenine?

Answer 1

The forensic scientist can assume that the number of adenine is always equal to the number of thymine, according to the base pair rule. Adenine matches with the other purine pair, thymine because it is the only thing to which it could have a hydrogen bond with. 

Answer 2

The number of adenine will be equal to the number of thymine
