Question

Which of the following is incorrect about reporter gene

• A. gene whose phenotype can be assayed in a transformed organism
• B. $\beta -$ galactosidase gene is an example of reporter gene
• C. test gene that is fused to the upstream region of the cloned gene
• D. none

Answer 1

Answer: (D)

none

Reporter genes are those genes that are attached to the genes of the other organisms to obtain their process and details. These genes are often used to obtain gene of interest or desirable gene, sometimes they are also used as a selectable marker. They are placed at the upstream position of the gene of interest to contain their gene expression and functions. Some of the examples are lac Z, GFP (Green fluorescent protein) etc. Lac Z is the reporter genes and acts upon the beta-galactosidase gene.

So, the correct option is 'none'.
