Detailed explanation-1: -Each end of DNA molecule has a number. One end is referred to as 5’ (five prime) and the other end is referred to as 3’ (three prime). The 5’ and 3’ designations refer to the number of carbon atom in a deoxyribose sugar molecule to which a phosphate group bonds.
Detailed explanation-2: -The complementary DNA strand of the sequence ATGC will be TACG. The complementary base pairing in DNA is as per the Chargaff’s rules. According to these rules, purines always hydrogen bond with pyrimidines and vice-versa. Thus, adenine always hydrogen bonds with thymine by two hydrogen bonds.
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.
