Solution
The correct option is C Reporter A reporter gene is a gene cloned with a DNA sequence of interest inserted into an expression vector followed by transfer to target tissues. After transfer, the cells are assayed to detect the presence of the reporter by measuring the reporter protein or its enzymatic activity. A good reporter gene is identified easily and can be measured quantitatively when it is expressed in the tissue of interest. They are used as indicators to study gene expression in target tissue for pharmaceutical and molecular biology research. So, the correct option is option C.
