In 1950, Erwin Chargaff observed that there are relationships between the relative amounts of the nucleotide bases adenine (A), thymine (T), cytosine (C), and guanine (G) in DNA. These relationships became known as Chargaff's rules.

When analyzing the nucleotide composition of double-stranded DNA, which of the following would you expect to be TRUE based upon Chargaff's rules?

Select ALL that apply.

A

The number of guanines is equal to the number of thymines.

B

The number of adenines is equal to the number cytosines.

C

The number of thymines is equal to the number of adenines.

D

The number of guanines is equal to the number of adenines.

E

The sum of the numbers of cytosines and adenines is equal to the sum of the numbers of guanines and thymines.

F

The sum of the numbers of guanines and cytosines is equal to the sum of the numbers of thymines and adenines.
