Answer:
GACCTG (the fourth option)
Explanation:
To find the correct complementary strand, we need to know this simple rule:
T always pairs with A and C always pairs with G.
So whatever letter you have in the DNA strand, the complementary strand will have the complement to it. In this case, we have CTGGAC. The complement of C is G, for T it is A, and so on. Therefore, the correct complementary strand is GACCTG (the fourth option).
