In 1970s and 1980s, molecular biologists discovered that the hormone testosterone, binds a receptor protein that recognizes a 15 base pair DNA sequence. As a result, genes that contain this sequence can be activated by testosterone. Scientists called this hormone, an enhancer and exploited its property to turn genes off or on. In your class, you observed a similar mechanism related to a milk protein. Answer the following questions:
i. What is the important molecular phenomenon or concept that you learned in class that exactly mimics the testosterone concept explained above?
ii. In the concept you learned in class, what organism does the similar process occur, and what biomolecule takes the place of testosterone?
iii. How can the above phenomenon be used to treat cancer?
iv. How can the above mechanism aid in improving the immune system?
