base pairingn.

Brit.

/ˈbeɪs ˌpɛːrɪŋ/, U.S.

/ˈbeɪs ˌpɛ(ə)rɪŋ/

Origin: Formed within English, by compounding. Etymons: base n.¹, pairing n.²

Etymology: < base n.¹ + pairing n.², after base pair n. Compare slightly later base-pair v.

Biochemistry.

The combining of two bases to form a base pair; an instance of this.See note at base pair n.

1956 Proc. National Acad. Sci. U.S.A. 42 62 This base-pairing scheme is shown in Figure 2, where it is seen that N_base—C_sugar bonds are related by a twofold axis parallel to the helical axis.

1960 V. R. Potter Nucleic Acid Outl. I. iii. 83 These figures describe the spatial relationships for the four possible base pairings found in the double helix.

1988 P. W. Kuchel et al. Schaum's Outl. Theory & Probl. Biochem. vii. 183 DNA is a duplex molecule in which two polynucleotide chains (or strands) are linked to one another through specific base pairing.

2002 Guardian 2 July i. 16/2 The discovery of what became widely known as base-pairing carried weight because Chargaff was a hugely respected experimental scientist.
