A scientist examines a genetic mutation in a DNA model.

Definition
  1. Noun:
    • (Genetics) A change in genetic structure: A genetic mutation is any event that alters the genetic material (DNA or RNA sequence) of an organism.
    • An alteration in the inherited nucleic acid sequence: It refers specifically to a change in the sequence of nucleotides that constitutes the genotype, which can be passed to offspring.
Usage Examples
  • Noun:
    • A single genetic mutation can sometimes cause a hereditary disease.
    • Scientists studied the genetic mutation responsible for the new trait in the plant population.
    • The genetic mutation was spontaneous and not inherited from either parent.
Advanced Usage
  • "to carry a genetic mutation": to possess a specific alteration in one's genes, which may or may not cause a visible effect.
    • She carries a genetic mutation that increases her risk for certain cancers.
  • "to undergo a genetic mutation": to experience a change in genetic sequence.
    • The virus appears to have undergone a genetic mutation, making it more transmissible.
Variants and Related Words
  • Mutate (verb): To undergo or cause to undergo a mutation.

  • Mutagen (noun): A physical or chemical agent that causes genetic mutation.

Synonyms
  • Mutation: The more general term, often used interchangeably with .
  • Genetic alteration: A formal synonym emphasizing the change in genetic material.
  • Sequence variant: A neutral term often used in genomic studies to describe a difference from a reference sequence.
Related Phrases
  • Point mutation: A mutation affecting a single nucleotide base.
    • A point mutation changed a single amino acid in the protein.
  • Frameshift mutation: A mutation caused by insertions or deletions that shifts the way the sequence is read.
    • The frameshift mutation rendered the gene non-functional.
  • Somatic mutation: A mutation that occurs in non-reproductive cells and is not inherited.
