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.

<h3>what is osmosis ?</h3>
Osmosis can be the passive process where the molecules move from the region of higher concentration to lower concentration until the concentrations become equal on either side of the membrane with out expenditure of external energy.
Gases and liquids are solvent undergo the process of osmosis; It can be Endosmosis where a substance in a hypotonic solution, the solvent molecules move inside the cell and the cell becomes turgid by a process of DE plasmolysis.
