base-pairing
Low/TechnicalAcademic/Scientific
Definition
Meaning
The specific hydrogen bonding between complementary nitrogenous bases in DNA or RNA (adenine with thymine or uracil, guanine with cytosine).
More broadly, the principle of complementary binding between nucleotides which ensures accurate replication of genetic material and drives processes like transcription and translation.
Linguistics
Semantic Notes
Primarily a noun, but can be used attributively as an adjective (e.g., base-pairing rules). The term is inseparable from the context of molecular biology and genetics.
Dialectal Variation
British vs American Usage
Differences
No significant lexical or spelling differences. Hyphenation is standard in both varieties.
Connotations
Identical technical connotations in scientific discourse.
Frequency
Frequency is identical and confined to relevant scientific fields.

Examples
By Part of Speech
verb
British English
- The nucleotides are designed to base-pair according to Watson-Crick rules.
American English
- The synthetic oligonucleotides will base-pair with their complements.
adjective
British English
- The researcher studied the base-pairing interactions in the new model.
American English
- Understanding base-pairing fidelity is crucial for genetic engineering.
Examples
By CEFR Level
- DNA replication depends on correct base-pairing.
- Adenine and thymine have a specific base-pairing.
- The enzyme's function is compromised by a single error in base-pairing during synthesis.
- The textbook explains the rules of complementary base-pairing in a clear diagram.
- The fidelity of the polymerase is attributed to its exonucleolytic proofreading activity, which excises misincorporated nucleotides resulting from erroneous base-pairing.
- Advanced sequencing techniques can detect even rare non-canonical base-pairing events within the genome.
Learning
Memory Aids
Mnemonic
Think of it as a zipper: 'Base-Pairing' is the 'PAIRING' of the teeth (bases) that zips the two strands of DNA together.
Conceptual Metaphor
A PRECISE LOCK-AND-KEY MECHANISM or a SPECIFIC HANDSHAKE, where only complementary shapes/partners bind correctly.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'базовое спаривание' which is a calque and sounds unnatural. The correct established term is 'спаривание оснований' or 'комплементарное связывание оснований'.
Common Mistakes
- Using it as a verb without nominalization (e.g., 'The bases base-pair' is awkward; prefer 'The bases undergo base-pairing').
- Confusing 'base-pairing' (the process/principle) with a 'base pair' (the unit).

FAQ
Frequently Asked Questions
No. 'Base-pairing' refers to the process or principle of complementary binding. A 'base pair' (e.g., an A-T pair) is the unit formed by that process.
Yes. Base-pairing is fundamental to RNA structure (e.g., in tRNA, rRNA) and function, with adenine pairing with uracil (instead of thymine).
In standard scientific writing, the hyphen is used, especially when the term functions as a compound modifier (e.g., base-pairing rules). It may occasionally appear as 'base pairing' in running text.
It refers to stable hydrogen-bonding patterns between bases that differ from the standard A-T/U and G-C pairs, often important in the complex 3D structures of RNA molecules.
