A stands for Adenine and T stands for Thyamine
Adenine and Thyamine are the only ones that go together...so whenever you see an A, it corresponds with T...and vice versa
C stands for Cytosine and G stands for Guanine
Cytosine and Guanine are the only ones that go together...so whenever you see C, it corresponds with G...and vice versa
P.S. I'm pretty sure that's what the question was asking, correct me if I'm wrong..i remember doing something similar in 7th grade
