Transposon - Meaning, Definition & English Examples
A transposon is a segment of DNA that can change its position within a genome, sometimes causing mutations or altering genetic traits. It is also called a jumping gene.
Definition:
A DNA sequence that can change its position within a genome, often causing mutations.
Synonyms:
jumping gene, mobile genetic element, transposable element
Part of Speech:
noun
Antonyms:
stable gene, fixed sequence (Note: True antonyms are rare for scientific terms.)
Common Collocations:
bacterial transposon, eukaryotic transposon, transposon insertion, transposon mutagenesis
Derivatives:
transposition, transposable
Usage Tips:
Use "transposon" when discussing genetic elements that move within DNA; avoid in non-scientific contexts.
Common Phrases:
"jumping gene, " "selfish DNA, " "mobile element" (Note: Phrases are more technical than idiomatic.)
Etymology:
From "transpose" (to change position) + "-on" (suffix for molecular units), coined in the 20th century.
Examples:
- 1. Scientists study transposons to understand genetic mutations.
- 2. Transposons can disrupt genes when they move to new locations.
- 3. Some diseases are linked to transposon activity in humans.
- 4. Bacteria use transposons to spread antibiotic resistance genes.
