Question

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? The gene that controls production of stem cells. The gene that controls production of skin cells. The gene that controls production of red blood cells. The gene that controls production of white blood cells.

Answer 2

The gene that controls production of white blood cells.

Step-by-step explanation:

Influenza (the flu) is caused by a virus which attacks the respiratory system. The body system views the influenza virus as a foreign body and certain signals are passed to the immune system. The immune system is responsible for fighting infections and diseases and the major cells involved are the white blood cells(leukocytes).

This makes the gene that controls production of white blood cells to be widely expressed in the body of someone who contracts the influenza virus.
