Question

Influenza (the flu) is caused by a virus that attacks the respiratory system. Which type of gene is most likely to be widely expressed in the body of someone who contracts the influenza virus?

the gene that controls the production of stem cells
the gene that controls the production of skin cells
the gene that controls the production of red blood cells
the gene that controls the production of white blood cells

Answer 1

the gene that controls the production of white blood cells

Reason: Influenza triggers an immune response, so genes promoting white blood cell production and activity are upregulated widely to fight the viral infection.
