Definition(s)
- 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

from the University of Washington and Children's Health System, Seattle
- Two bases which form a "rung of the DNA ladder." A DNA nucleotide is made of a molecule of sugar, a molecule of phosphoric acid, and a molecule called a base. The bases are the "letters" that spell out the genetic code. In DNA, the code letters are A, T, G, and C, which stand for the chemicals adenine, thymine, guanine, and cytosine, respectively. In base pairing, adenine always pairs with thymine, and guanine always pairs with cytosine.
