basepair

DNA ladder step

A basepair is a unit of measurement for DNA and RNA, referring to the pairing of nucleotide bases (adenine with thymine or uracil, cytosine with guanine) that form the rungs of the double helix.

Scientists describe genome sizes in basepairs: The human genome contains about three billion basepairs.

Also written as two words or hyphenated: base pair, base-pair.
