What is mutation? Pronunciation and usage in English

Let's break down how to use the word "mutation" in English. It's a word with a few different, distinct meanings, so understanding the context is key.

1. Biological Mutation (Most Common)

• Definition: In biology, a mutation is a change in the DNA sequence of an organism. It’s essentially a random alteration in the genetic code.
• How to use it:
  • "DNA mutation": This refers to a specific change in the DNA itself. “Scientists are studying the DNA mutations that cause cancer.”
  • "Gene mutation": A change in a specific gene. “A mutation in the BRCA1 gene increases a woman's risk of breast cancer.”
  • "Germline mutation": A mutation that occurs in sperm or egg cells and is therefore passed down to future generations. “The researchers discovered a germline mutation linked to the disease.”
  • "Somatic mutation": A mutation that occurs in a body cell after fertilization and is not passed on to offspring. “The radiation exposure caused somatic mutations in his skin cells.”
• Examples:
  • “Mutations can be harmful, beneficial, or neutral.”
  • “Natural selection acts on mutations, favoring those that increase an organism's chances of survival.”
  • "The mutation allowed the bacteria to become resistant to the antibiotic."

2. Figurative/Metaphorical Mutation

• Definition: Outside of biology, "mutation" can describe a significant and often negative change in something that was previously stable or consistent. It’s used to suggest a radical and often disruptive shift.
• How to use it:
  • Often used with nouns: “There’s been a complete mutation of the company’s culture.” “A mutation of his personality occurred after the accident.” “A mutation in the relationship resulted in distance and misunderstandings.”
• It often implies a loss of something original or desirable. It suggests a corrupting influence.
• Examples:
  • "The new regulations caused a mutation in the industry." (meaning a drastic and often negative change)
  • “The politician's stance underwent a disturbing mutation during the campaign." (suggesting he became someone he wasn't before)
  • “The story mutated as it was retold over generations.” (meaning it changed significantly and perhaps lost its original meaning.)

3. Less Common Uses

• “Mutation of ideas”: This refers to a radical change or evolution in a thought or concept. (Less frequent than the figurative use)

Key Differences & Considerations:

Feature	Biological Mutation	Figurative Mutation
Context	Biology, genetics	General use, often societal/cultural
Nature of Change	Random DNA change	Significant, often negative shift
Implication	Adaptations, evolution	Disruption, corruption, loss

Tips for Using "Mutation" Correctly:

• Be clear about the subject: Is it DNA? A company? A person? A relationship?
• Consider the tone: The figurative use of “mutation” often carries a negative connotation.
• Use synonyms when appropriate: Depending on the context, words like “change,” “transformation,” “shift,” or “evolution” might be better fits.
