Complementarity refers to the fact that each nucleotide base in one strand of DNA is paired with a specific complementary base in the opposite strand, such that A pairs with T and C pairs with G. This base pairing is necessary for the double-stranded nature of DNA, as it allows hydrogen bonds to form between the complementary bases, holding the two strands together.
