Step-by-step explanation:
dna base sequences are complementary to mrna base sequences.
There are 4 base sequences in DNA:
adenine (a), thymine (t), guanine (g) and cytosine (c). In complementary base pairing a pairs with t, and c pairs with g via hydrogen bonding.
However mRNA does not have the same four bases. In RNA, thymine is replaced with uracil (u), so a pairs with u, and c pairs with g.
