Detailed explanation-1: -The complementary DNA strand of the sequence ATGC will be TACG.
Detailed explanation-2: -Adenine makes the double bond with thymine while guanine makes the triple bond with cytosine which means adenine and thymine are complementary base pairs and cytosine and guanine are complementary base pairs. The complementary sequence for the DNA strand 5’ ATCGAACGT 3’ is 3’ TAGCTTGCA 5’.
Detailed explanation-3: -Solution : (c) Adenine always pairs with thymine and cytosine always pairs with guanine. Thus, sequence of bases on complementary strand would be TACGTACGT.
Detailed explanation-4: -The answer is B. 3’-TGCCAT-5’ A strand of a DNA molecule has a base sequence of 5’-ACGGTA-3’. Its complementary strand will have a base sequence according to the base-pairing rule that states T forms pair with A (and vice versa) and C forms pair with G (and vice versa).
