Correct answer is b ( Purines bond to pyrimidines ) .
In DNA molecules nucleotides bond together according to the nitrogenous bases. Purines bond to pyrimidines described nitrogenous bases bond together.
The rules of base pairing (or nucleotide pairing) are: A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G) .
