Question

value: 2
specialized genes:
○ a. are active in all cells
○ b. are responsible for eye color in all humans
○ c. code for proteins with specific functions in certain cells
○ d. dont exist

Explanation:

Specialized genes are not active in all cells (so option a is wrong). Eye - color genes are a type of specialized genes but not all specialized genes are about eye color (so option b is wrong). Specialized genes do exist (so option d is wrong). Specialized genes code for proteins with specific functions in certain cells. For example, in red blood cells, genes related to hemoglobin production (a specialized protein for oxygen transport) are active.

Answer:

C. code for proteins with specific functions in certain cells
