Four different bases make up DNA, and the sequence of these bases encodes the information that determines an organism’s traits. Select the option that correctly lists the four bases and describes how they pair to make the rungs of the DNA ladder.

• The four bases are uracil (U), arginine (A), cyclosine (C) and guarine (G). U pairs with A and C pairs with G.

• The four bases are adenine (A), guanine (G), cytosine (C) and thymine (T). A pairs with T and C pairs with G.

• The four bases are alanine (A), gorine (G), cyclosine (C) and thyidine (T). A pairs with T and C pairs with G.
