Definition
Noun: The occurrence or process that causes a genetic mutation. It refers to an event or the action of an agent that induces a change in the structure of genetic material (DNA or RNA).
Usage
"Mutagenesis" is a technical term used primarily in biology, genetics, and medicine. It describes the initiation or causation of a mutation, not the mutation itself. It is often used to discuss laboratory techniques, environmental factors, or disease mechanisms.
Examples
- In a scientific context:
- The researcher studied the mutagenesis caused by ultraviolet radiation.
- Site-directed mutagenesis is a common laboratory technique for studying gene function.
- Describing a process:
- The chemical's role in carcinogenesis is linked to its mutagenesis in epithelial cells.
Advanced Usage
- "Site-directed mutagenesis": A precise molecular biology method to introduce specific, pre-determined changes into a DNA sequence.
- They used site-directed mutagenesis to create a mutant version of the protein.
- "Insertional mutagenesis": A process where a piece of DNA is inserted into a genetic sequence, disrupting the function of a gene.
- The retrovirus caused disease through insertional mutagenesis.
Variants and Related Words
- Mutagen (n): A physical or chemical agent that causes mutagenesis (e.g., X-rays, certain chemicals).
- Mutagenic (adj): Having the ability to cause mutagenesis.
- The substance was found to be mutagenic in bacterial tests.
- Mutant (n/adj): An organism or gene carrying a mutation; resulting from mutation.
Synonyms
- Mutation induction: The process of causing mutations.
- Genotoxic event: An event that damages genetic information (a broader term that often includes mutagenesis).
Related Phrases
- "Mechanism of mutagenesis": The specific way in which an agent causes genetic change.
- The paper explored the mechanism of mutagenesis for the new compound.
- "Rate of mutagenesis": The frequency at which mutations are induced.
- The rate of mutagenesis was higher in the exposed population.
Noun
- an event capable of causing a mutation
