Answer:
The number of adenine bases will be equal to the number of thymine bases.
Step-by-step explanation:
A DNA molecule is a double-stranded molecule made up of nucleotide bases. There are four (4) nucleotide bases that make up the DNA viz: Adenine, Guanine, Cytosine, and Thymine.
According to Chargaff, who postulated the complementary base pairing rule that states that I the DNA molecule, Adenine base always hydrogen bond with Thymine base and Guanine base always hydrogen bond with Cytosine base i.e. A-T, G-C. Chargaff also found out that the amount of Pyrimidines (Cytosine and Thymine) are equal to one another, likewise the Purines(Adenine and Guanine).
According to Chargaff, the number of Adenine base equals the number of Thymine base that it pairs while the same occurs for Guanine and Cytosine pair. All bases total 1. Hence, the forensic scientists can assume that the number of Adenine base in the DNA is the same as the number of Thymine base.
