In simple terms, Gene expression can be stated as the process by which the heredity details in a gene sequence a be made into a functional gene.
<u>Explanation:</u>
- The odd one for this question is probably would be "it occurs because of cellular signals within your body".
-  It explains how a cell functions. In Gene expression, the gene encodes the protein and the message from DNA to RNA gives the cell functions.
- It is the specific combination of genes that are turned on or off. It can be stated as the process of turning off and turning on, it acts as a switch to on and off it is known as the gene expression or gene regulation.

Answer:
Some bacteria are used as indicators because if they are present in the product, we can say that it is a product with the presence of pathogens that will cause diseases. Some of them are: total coliforms, fecal coliforms and enterococci. 
To be a good indicator they must have a correlation with the pathogens and be more abundant than them. Its presence in a food indicates the possible presence  simultaneous pathogen microorganisms. For example, E. coli has been used as  Index of possible presence of pathogens of enteric origin in water and food
