1. Why do scientists think that lactose affects the production of Beta galactosidase?

2. What is the original source of information for the sequence of amino acids in a protein?

3. In what part of the cell does protein synthesis occur?

4. Which step in protein synthesis is blocked by Chloramphenicol?


5. How will you distinguish between the hypothesis that the DNA-RNA pathway is directly activated by lactose to produce beta galactosidase compared to the hypothesis that lactose is necessary for the activation of already existing beta galactosidase proteins?
