Brianna and Isaac are analyzing a DNA sample in their biology class. According to Chargraff's Rule, if Adenine (A) is 30% of the sample DNA, what is the percentage of Cytosine (C)?

Answer

According to Chargaff's Rule, the amount of Adenine (A) equals the amount of Thymine (T), and the amount of Cytosine (C) equals the amount of Guanine (G). If Adenine is 30%, then Thymine is also 30%. This leaves 40% for Cytosine and Guanine combined. Therefore, the percentage of Cytosine (C) is 20%.
