deoxyribonucleotide
C2Technical/Scientific
Definition
Meaning
A single building block molecule, consisting of a deoxyribose sugar, a phosphate group, and one of four nitrogenous bases, that polymerizes to form DNA.
Any of the monomeric units that link together to create the polymer chain of deoxyribonucleic acid (DNA); the specific nucleotide unit in DNA genetics and biochemistry.
Linguistics
Semantic Notes
Specifically denotes a nucleotide in DNA, as opposed to a ribonucleotide in RNA. The term is precise and unambiguous within its field.
Dialectal Variation
British vs American Usage
Differences
Spelling and pronunciation are consistent. No significant lexical or usage differences.
Connotations
Identical technical meaning in both varieties.
Frequency
Exclusively used in technical contexts (biochemistry, molecular biology, genetics) in both regions with equal frequency.

Examples
By Part of Speech
adjective
British English
- The deoxyribonucleotide composition was analysed.
- A deoxyribonucleotide triphosphate precursor is required.
American English
- The deoxyribonucleotide sequence was determined.
- Deoxyribonucleotide metabolism is a key pathway.
Examples
By CEFR Level
- DNA is a long molecule made from many linked deoxyribonucleotides.
- Scientists can identify which deoxyribonucleotide is present at a specific position in a gene.
- Polymerase enzymes catalyse the addition of the correct deoxyribonucleotide to the growing DNA strand during replication.
- The specificity of the DNA polymerase for its deoxyribonucleotide substrates is crucial for fidelity.
Learning
Memory Aids
Mnemonic
Think: DEOXY (one less oxygen than ribose) + RIBO (ribose sugar) + NUCLEO (nucleic acid core) + TIDE (as in nucleotide). It's the 'tide' of building blocks that makes the DNA 'deoxy' sea.
Conceptual Metaphor
A LEGO brick for building DNA; a letter in the genetic alphabet.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid calquing as "дезоксирибонуклеотид" without understanding it's a specific biochemical term, not a general word.
- Do not confuse with "нуклеотид" (nucleotide), which is the broader category.
Common Mistakes
- Misspelling as 'deoxyribonucleatic', 'deoxiribonucleotide'.
- Confusing it with 'ribonucleotide'.
- Using it in non-scientific contexts.

Frequently Asked Questions
A nucleotide is the general term for a monomer consisting of a sugar, phosphate, and base. A deoxyribonucleotide is a specific type of nucleotide where the sugar is deoxyribose, making it a building block of DNA.
No, it is a highly technical term exclusive to fields like biochemistry, genetics, and molecular biology.
In British English: /diːˌɒksɪˌraɪbəʊˈnjuːklɪətaɪd/. In American English: /diˌɑksɪˌraɪboʊˈnuːkliəˌtaɪd/. The key is breaking it down: dee-OX-ee-RYE-bo-NEW-klee-oh-tide (UK) / dee-OK-see-RYE-bo-NOO-klee-uh-tide (US).
Yes, as a free molecule (often as a triphosphate, e.g., dATP), it is a substrate for DNA synthesis. In cells, they also exist polymerized into DNA strands.
