The two complementary, nitrogen-rich molecules held together by weak chemical bonds. Two strands of DNA are held together in the shape of a double helix by the bonds between their base pairs.
(bp)
Two nitrogenous bases paired together in double-stranded DNA by weak bonds;
specific pairing of these bases (adenine with thymine and guanine with cytosine)
facilitates accurate DNA replication; when quantified (e.g., 8 bp), refers
to the physical length of a sequence of nucleotides
