6. Arrange the following phrases in order to indicate the sequence of events that would occur as a result of a gene mutation in the gene that codes for hemoglobin protein. 1. Gene mutation (change in the DNA code in the gene for hemoglobin) 2. Change in the mRNA code 3. Change in the amino acid sequence of the hemoglobin protein 4. Change in the structure or function of body cells or tissues 5. Change in the shape of a hemoglobin protein 6. Change in the ability of the hemoglobin protein to function properly 7. Change in characteristics and symptoms of a genetic disease

1. What is a gene? Describe the function, structure, and location within the cell. 1. How long are each of your peptide chains (how many amino acids are present)? 2. What differences exist between your two transcripts? What about your translated product? 3. Hb A represents a section of the 626 base normal hemoglobin beta mRNA sequence. Hb S is from the sickle cell hemoglobin. Is the mutation found in sickle cell hemoglobin a point mutation or a frameshift mutation? 4. Does the sickle cell mutation result in a missense mutation, silent mutation or nonsense mutation? Why?
