The genes required to produce the enzymes needed to digest lactose sugar are under the control of one promoter , meaning they are transcribed at the same time.
What is enzyme and promoter?
- According to genomics, a promoter is a region of DNA upstream of a gene where pertinent proteins bind to start that gene's transcription.
- A molecule of RNA is created as a result of the transcription.
- A promoter is a section of DNA where a gene first begins to transcribe.
- In expression vectors, promoters are crucial because they control how RNA polymerase binds to DNA.
- DNA is converted to mRNA by RNA polymerase, and mRNA is then translated into a useful protein.
- Any element that is added to a catalyst to boost activity or selectivity is called a promoter.
- Examples include the addition of tin to platinum reforming catalysts to enhance coke formation selectivity and the addition of chloride to isomerization catalysts to boost activity.
