Among the given base pairing situations, whether the base paring includes two DNA strands, a DNA strand and a RNA strand, or it might includes either two DNA strands or a DNA strand and an RNA strand has to be predicted. Concept introduction: DNA contains double helical strands along with the complementary base pairs. The four complementary bases of DNA are adenine (A), thymine (T), guanine (G) and cytosine (C). RNA contains the complementary base pairs. The four complementary bases of RNA are adenine (A), uracil (U), guanine (G) and cytosine (C).
