Detailed explanation-1: -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-2: -DNA base pair. Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together.
Detailed explanation-3: -Answer and Explanation: 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.
Detailed explanation-4: -A strand of DNA with the sequence AACTTG will have a complimentary strand with the sequence. Explanation: There are four nitrogenous bases. They help in relation of one of the strand of the DNA with the others strand.
