C)tRNA
D)synthetic DNA (one strand all A, the other all T)
E)all of the above

Quizplus · Accepted Answer

Chargaff's equivalence states that the amount of adenine (A) in DNA is equal to the amount of thymine (T), and the amount of cytosine (C) is equal to the amount of guanine (G). Synthetic DNA with one strand all A and the other all T satisfies this criteria. The other choices, mRNA and tRNA, are single-stranded RNA molecules and do not have the same base pairing rules as DNA. Single-stranded DNA could potentially have any combination of bases and therefore may not show Chargaff's equivalence.
