Chargaff's rules state that the amount of adenine equals the amount of:

  1. Guanine
  2. Cytosine
  3. Uracil
  4. Thymine
Show answer and solution

Correct answer: D. Thymine

1. Cytosine equals guanine too. 2. A equals T and G equals C. 3. Ratios of A+T to G+C differ by species. _Source: OpenStax Biology 2e, Chapter 14, DNA Structure and Function (CC BY 4.0)._
