Based on Chargaff's rule, the percentage of thymine bases in the chicken DNA should be around 28.8%
What is Chargaff's rule?
The rule states that for every DNA molecule, the ratio of purine bases (Adenine and Guanine) to pyrimidine bases (Cytosine and Thymine) is 1:1.
It also states that Guanine must be equal to Cytosine while Adenine must be equal to Thymine.
Following this rule and considering that the amount of Adenine in the chicken is 28.8%, the percentage of Thymine would also be 28.8%.
