Explanation:
Detailed explanation-1: -So if one strand is ATGCTTGA then the complementary strand will be TACGAACT.
Detailed explanation-2: -The correct answer is (d): 5’ TACCGA 3’. Based on complementary base pairing rules, T pairs with A, whereas C pairs with G. Hence, the complementary sequence for 3’ ATGGCT 5’ starting from the 5’ end is 5’ TACCGA 3’.
Detailed explanation-3: -In DNA, adenine always pairs with thymine (A-T), and guanine always pairs with cytosine (G-C).
