DEF

A pair of nucleotides in the complementary strands of a [nucleic acid] molecule that interact through hydrogen bonding across the axis of the helix.

OBS

Because DNA is double-stranded, the lengths of molecules are described as so many base pairs (bp).

OBS

[In general,] lengths of RNA molecules [are not] expressed in bp because most RNAs are single-stranded.

OBS

[In DNA,] one of the nucleotides in each pair is a purine (either adenine or guanine), and the other is a pyrimidine (either thymine or cytosine). Because of their spatial configuration, adenine always pairs with thymine, and guanine always pairs with cytosine.
