Step 1
C. The hormone prolactin allows for the expression of the casein gene.
Answer
In the provided diagrams, it is evident that prolactin plays a crucial role in activating the casein gene. When prolactin is present, it inactivates ribonuclease, allowing for the production of casein mRNA. This mRNA is essential for synthesizing casein protein, indicating that prolactin is vital for the expression of the casein gene.
