The correct answer is: c. An operon is a region of DNA that codes for a series of functionally related genes under the control of the same promoter.
Operons contain cluster of genes that are transcribed together into mRNA or are not expressed at all. Formed mRNA undergos splicing to create monocistronic mRNAs so that can be translated separately. Operons are more often found in prokaryotic cells but it can appear in eukaryotic cells and in viruses.
The answer is; UV (ultraviolet)
The security pens use UV light to illuminate some marking on an object,such as a watermark, to identify its authenticity or owner. The markings are usually invisible to the naked eye under visible light. The marks are only visible when illuminated with UV light. This is because the marking is made of a fluorescent material that absorbs light of a shorter wavelength (this case UV) and emits a longer wavelength (this case visible light).
