The expression of a transgene in the target tissue is identified by a ___________?
Correct answer: D. Reporter
- A. Transgene
- B. Promoter
- C. Enhancer
- D. Reporter
Explanation
A reporter gene produces an easily detected signal, such as fluorescence or a coloured product, when the transgene is expressed in the target tissue. The promoter is the likely alternative because it controls transcription, but it does not itself provide the detectable output used to identify expression.
