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.

1. an event capable of causing a mutation
