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. The binding of these base pairs forms the structure of DNA.
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: -Adenine always bonds with thymine, and guanine only bonds with cytosine. In RNA however, uracil (U) is substituted for thymine instead. So, in translation, adenine turns into thymine, and guanine turns into cytosine, and vice-versa. So, the complementary side would read TACGGCA .
