The following template DNA sequence is part of the human lactase gene TAC-CTC GAC-AGA-ACC-CTA-CAT-CAG-AAA⦠a. Transcribe the DNA strand into RNA 6 points) b. Translate the RNA strand into amino acids (5 points) c. Bob prepared four containers that had the following contents: A Yeast only + warm water B: Yeast with powdered milk + warm water C: Yeast with powdered milk + crushed lactaid caplet + warm water D: Yous with powdered milk + boiled crushed lactaid caplet + warm water the water temperature was not measured Write a hypothesis stating which container should have the most enzyme activity (10 points) d. Bob obtained the following results. The numbers under the letters indicate the foam height in mm for the respective container: Time min РB C 0 0 0 0 0 0 0 D 0 0 5 8 11 14 17 20 0 0 0 0 0 0 o 0 0 0 0 D 0 Do these results support your hypothesis? Why or why not? Look for possible sources of experimental error if his data does not support your hypothesis. Assume he added the correct ingredients in the respective containers A.D. (10 points) e. Lactose is a sugar that is unable to be digested in infants who have a mutation in the lactase gene. This is a form of lactose intolerance. There needs to be two copies of the mutated gene in order for an infant to have the disease. If Bob and Karen do not have lactose intolerance but their infant child Daniel has it. Explain using a Punnett square why this is case. (5 points)
