Definition
  1. Noun:
    • A change or alteration in form or qualities: "Mutation" refers to the process or result of something changing or being altered, often in a significant way.
    • (Genetics) Any event that changes genetic structure: In biology, a "mutation" is a change in the DNA sequence within a gene or chromosome of an organism, which can lead to new traits.
    • (Biology) An organism that has characteristics resulting from chromosomal alteration: "Mutation" can also refer to the individual organism or the new trait itself that results from a genetic change.
Usage Examples
  • General Change:
    • The rapid mutation of technology makes it hard to keep up. (The fast change in technology makes it hard to keep up.)
    • The artist's style underwent a complete mutation over the years. (The artist's style experienced a complete alteration over the years.)
  • Genetics:
    • A single gene mutation can cause the disease. (A single gene alteration can cause the disease.)
    • Scientists study DNA mutations to understand evolution. (Scientists study DNA changes to understand evolution.)
  • Resulting Organism/Trait:
    • The white flower is a mutation of the common red variety. (The white flower is a variant resulting from a genetic change of the common red variety.)
Advanced Usage
  • "Point mutation": A genetic mutation where a single nucleotide base is changed, inserted, or deleted.
    • A point mutation in the hemoglobin gene causes sickle cell anemia.
  • "Spontaneous mutation": A mutation that occurs naturally without a known cause.
    • Spontaneous mutations are a source of genetic variation in populations.
  • "Mutation rate": The frequency at which mutations occur in a given gene or organism over time.
    • The mutation rate of the virus is being closely monitored.
Variants and Related Words
  • Mutate (verb): To undergo or cause to undergo mutation.
    • The virus can mutate rapidly.
  • Mutant (noun/adjective): An organism or gene resulting from mutation; having undergone mutation.
    • The comic book features a team of mutants.
  • Mutagen (noun): An agent, such as radiation or a chemical substance, that causes genetic mutation.
    • Certain chemicals are known mutagens.
Synonyms
  • Alteration: A change, typically one that makes something different.
  • Variation: A change or difference in condition, amount, or level.
  • Transformation: A thorough or dramatic change in form or appearance.
  • (In genetics) Genetic change: A change in the genetic material.
Related Phrases
  • "To undergo a mutation": To experience a genetic or fundamental change.
    • The bacteria underwent a mutation that made it resistant to the antibiotic.
  • "Mutation breeding": The process of exposing seeds to chemicals or radiation to induce mutations and develop new crop varieties.
    • Mutation breeding has been used to create disease-resistant wheat.
Related Idioms
  • "A genetic lottery": This idiom, while not containing the word "mutation," relates to the random nature of genetic inheritance and mutation.
    • Which traits you inherit is like winning the genetic lottery.
