Gene expression within the body is controlled by the cells, which determine when a specific gene should or should not be expressed. influenza (the flu) is caused by a virus that attacks the respiratory system. which type of gene is likely to be widely expressed in the body of someone who contracts the influenza virus? a. the gene that controls production of stem cells. b. the gene that controls production of skin cells. c. the gene that controls production of red blood cells. d. the gene that controls production of white blood cells.

d. The gene that controls production of white blood cells.

Explanation:

In a body infected with Influenza the cells will encourage the expression of the gene producing white blood cells because this kind of cells, called also leukocytes, protect the body against infectious diseases and foreign invaders. There are many types of white cells, for example: neutrophils, eosinophils, basophils, lymphocytes, and monocytes acting against specific types of invaders.

Lymphocytes acts against virus as the Influenza, therefore, the gene that controls white blood cells will probably be widely expressed to produce many lymphocytes.
