A forensic scientist is trying to find out the number of adenine bases in the DNA sample that he obtained from a crime scene.
What can he assume about the number of adenine?
The number of adenine bases will be equal to the number of guanine bases.
The number of adenine bases will be equal to the total of all the other bases.
The number of adenine bases will be equal to the number of thymine bases.
The number of adenine bases will be half of the number of cytosine bases.

The number of adenine bases will be equal to the number of thymine bases.
Reason: In double‑stranded DNA A pairs with T (Watson–Crick base pairing / Chargaff's rule), so A = T and G = C. (If the sample were single‑stranded or highly degraded you couldn't assume this.)
