mutagenize
RareTechnical/Scientific
Definition
Meaning
To treat (an organism or genetic material) with a mutagen in order to induce mutations.
A deliberate, experimental process of inducing genetic changes, often used in research to study gene function, create genetic variation, or develop new strains.
Linguistics
Semantic Notes
The term is almost exclusively used in genetics, molecular biology, and related life sciences. It implies a controlled, agent-induced process, as opposed to spontaneous mutation. Can sometimes be used metaphorically in a very limited technical context (e.g., in software testing to describe inducing faults).
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or usage. Both use the '-ise' spelling, though in American English, the '-ize' variant is equally or more common. British dictionaries often list 'mutagenise' first.
Connotations
None beyond the shared technical/scientific register.
Frequency
Equally rare in both varieties, confined to specialist literature.

Examples
By Part of Speech
verb
British English
- The researchers will mutagenise the bacterial culture overnight with ethyl methanesulfonate.
- We mutagenised the seed stock to create novel phenotypic variants.
American English
- The lab plans to mutagenize the fly population using X-rays.
- They successfully mutagenized the plasmid to disrupt the gene of interest.
adjective
British English
- The mutagenised library contained thousands of novel variants.
- We analysed the mutagenised strain for auxotrophic requirements.
American English
- The mutagenized yeast cells were plated on selective media.
- Sequencing revealed the precise site of the mutagenized base.
Examples
By CEFR Level
- Scientists sometimes mutagenize plants to study how genes work.
- To find a bacteria that can survive the chemical, they mutagenized a large sample.
- The team employed a chemical mutagen to systematically mutagenize the entire genome of the model organism.
- After we mutagenize the cell line, we will employ a high-throughput screen to identify clones with the desired phenotype.
Learning
Memory Aids
Mnemonic
Imagine a GENIUS (sounds like 'genize') in a lab who uses a MUTant AGENt to change DNA: MUT-AGEN-IZE.
Conceptual Metaphor
GENETIC MATERIAL AS PLASTIC CLAY; The mutagen is a tool that reshapes it.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with general 'мутировать' (to mutate). 'Mutagenize' is causative: the scientist *causes* the mutation. A closer equivalent is 'обрабатывать мутагеном' or 'индуцировать мутации'.
Common Mistakes
- Using 'mutagenize' intransitively (e.g., 'The cells mutagenized' – incorrect). The subject is typically the agent or researcher.
- Confusing 'mutagenize' (the act of applying a mutagen) with 'mutate' (the process of change itself).

FAQ
Frequently Asked Questions
No. 'Mutagenize' is a transitive, causative verb meaning *to treat with a mutagen to cause mutations*. 'Mutate' is typically intransitive, meaning *to undergo mutation*. A scientist mutagenizes cells so that they will mutate.
Almost never. It is a highly technical term specific to genetics and molecular biology.
The related nouns are 'mutagenesis' (the process or instance of causing mutation) and 'mutagen' (the agent that causes the mutation).
Both are correct. 'Mutagenise' is more common in British English, while 'mutagenize' follows the typical American English '-ize' convention, though both spellings are understood globally in scientific literature.
