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 four chemical bases that make up the DNA code are adenine (A), guanine (G), thymine (T), and cytosine (C) which are arranged based on a specif organism such that they represent the information regarding the building of the organism

The chemical bases of the DNA are found in pairs consisting of two chemical bases which are then known as base pairs. The possible base pairs are;

Adenine (A) pairing with thymine (T)

Cytosine (C) pairing with Guanine (G)

Therefore, the forensic scientist should expect to find that the number of adenine bases will be equal to the number of thymine bases.

Since the scientist was trying to find out the number of adenine bases in the DNA sample, assumption that the number of adenine would be equal to the number thymine would help.

According to the base-pairing rule of Chargaff, adenine always pairs with thymine while guanine always pairs with cytosine.

Going by this rule, we can say that the number of adenine must be equal to the number of thymine while the number of guanine must be equal to the number of cytosine in any DNA.
