pseudogene
- noun
- /ˈsuːdəʊˌdʒiːn/
- Specialized
- A pseudogene is a segment of DNA that closely resembles a functional gene but does not produce a protein.
Examples
-
In most cases, such transferred fragments undergo rapid non-functionalization through pseudogene formation and DNA deletion and exhibit very low levels of transcription (37, 65).

Etymology
Pseudogene combines pseudo- from an old Greek word meaning 'false' and gene, so it literally means 'false gene'. Think of pseudonym, which means 'false name', because a pseudogene looks like a real gene but does not make a working protein, so it is called 'false'.
