Final answer:
The complementary base pair sequence for the given DNA sequence TTG-CAG is AAC-GTC.
Step-by-step explanation:
The complementary base pair sequence for the given DNA sequence TTG-CAG is AAC-GTC. In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). So, for each base in the original sequence, we pair it with its complement: T pairs with A, A pairs with T, C pairs with G, and G pairs with C. Therefore, the complementary base pair sequence for TTG-CAG is AAC-GTC.
