LowTechnical/Scientific
Definition
Meaning
A chemical compound that is one of the four nucleobases in the nucleic acids DNA and RNA. It pairs with thymine in DNA and with uracil in RNA.
A purine derivative essential in cell metabolism and energy transfer via molecules like ATP, ADP, and cAMP.

Examples
By Part of Speech
adjective
British English
- The adenine component was labelled.
- An adenine-deficient strain was used.
American English
- The adenine component was labeled.
- An adenine-deficient strain was used.
Examples
By CEFR Level
- DNA has four different bases: adenine, thymine, cytosine, and guanine.
- In DNA, adenine always forms a base pair with thymine via two hydrogen bonds.
- The researcher analysed the adenine content of the sample.
- A point mutation resulted in the substitution of guanine for adenine at the specified codon.
- The binding affinity of the protein for the adenine nucleotide was measured using a fluorescence assay.
Learning
Memory Aids
Mnemonic
Think: 'Add-A-Neen' to DNA. It's one of the building blocks you ADD to the structure.
Conceptual Metaphor
A 'letter' in the genetic 'alphabet' or a 'building block' in the DNA 'ladder'.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'адреналин' (adrenaline). 'Adenine' is 'аденин' in Russian.
Common Mistakes
- Mispronunciation: /əˈdiː.naɪn/ or /ˈæd.ə.naɪn/. Correct: /ˈæd.ə.niːn/.
- Confusing 'adenine' with 'adenosine' (a related nucleoside).

FAQ
Frequently Asked Questions
No, adenine is a nucleobase found in both DNA and RNA, as well as in many essential energy-carrying molecules like ATP and cofactors like NAD.
It is pronounced /ˈæd.ə.niːn/ (AD-uh-neen), with stress on the first syllable, in both British and American English.
In the context of DNA sequences, the letter 'A' is the standard abbreviation for the adenine base.
Adenine itself is not a common dietary supplement. However, its related compounds, like adenosine or vitamin B4 (adenine was once considered a B vitamin), are found in various metabolic pathways but are not typically supplemented in isolation.
