 Complementary sequences

In molecular biology, complementary sequences refer to sequences of nucleotides in DNA or RNA that can form hydrogen bonds with each other due to their base pairing rules. In DNA, the two strands of the double helix are complementary to each other; specifically: - Adenine (A) pairs with Thymine (T) via two hydrogen bonds. - Cytosine (C) pairs with Guanine (G) via three hydrogen bonds.
