Detailed explanation-1: -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-2: -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-3: -Replication relies on complementary base pairing, that is the principle explained by Chargaff’s rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).
Detailed explanation-4: -Different DNA sequences have a different arrangement of bases where the base-pairing rule is the same that adenine will bind to thymine, and guanine will bind to cytosine. So, according to the complementary base pairs, the base sequence AAGCAA will have TTCGTT as its complementary sequence.
