Question

a strand of dna contains the bases adenine, cytosine, cytosine, and guanine, in that order. which would be the order of the bases on the opposite strand of dna?
○ cytosine, adenine, adenine, and thymine
○ cytosine, thymine, thymine, and adenine
○ thymine, guanine, guanine, and cytosine
○ thymine, adenine, adenine, and cytosine

Explanation:

In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). Given the sequence adenine - cytosine - cytosine - guanine, the complementary sequence will be thymine - guanine - guanine - cytosine.

Answer:

thymine, guanine, guanine, and cytosine
