Answer: The complementary sequence of the DNA is GCTATCG.
The complementary sequence for RNA is CGAUAGC.
Explanation: There are five bases found in nucleic acids namely: Adenine, Uracil, Thymine, Cytosine and Guanine.
In DNA, Adenine pairs with Thymine while Guanine pairs with Cytosine. In RNA, Adenine pairs Uracil while Guanine pairs with Cytosine.
