The nucleotide sequence 5'-ATTGCAG-3' should base pair with
A) 5'-TAACGTC-3'.
B) 5'-CTGCAAT-3'.
C) 3'-ATTGCAG-5'.
D) 3'-CTGCAAT-5'.

Question

Quizplus · Accepted Answer

In base pairing, adenine (A) always pairs with thymine (T) and cytosine (C) always pairs with guanine (G). Therefore, for the given nucleotide sequence 5'-ATTGCAG-3', the complementary sequence would be 3'-TAACGTC-5'. Among the answer choices, only option B (5'-CTGCAAT-3') is complementary to the given nucleotide sequence, as it forms a complementary pairing with the sequence in question.
