Imagine that you are seeing a patient in a psychiatry clinic that has been diagnosed with severe bipolar disorder. Name two treatment options, one medicinal and one social, that may prove to be helpful to this patient.

Imagine you are given the DNA sequence for that codes for the protein beta-galactosidase (the enzyme that breaks down galactose) which has been extracted from a certain E. Coli colony. While viewing the sequence, you notice that the third codon has been mutated to code as a stop codon. How would you expect this to affect the certain E. Coli?
Due to the fact that the ribosome machinery would detect the premature stop codon, terminating the synthesis of the beta-galactosidase protein. This would prevent the protein from ever being produced, therefore the E. Coli would be unable to digest galactose.
