Unformatted text preview: Katie Linehan, Muting Lin, Laura Lombardini, Robert Maines HW # 6 Group #6 1. A 2. B 3. B 4. C 5. A 6. A. One significant similarity is that there is only one single promoter and a single termination signal, therefore everything is transcribed at once. B. In an operon the genes usually function in a related cellular process, while in this example they are functioning in several different processes. C. RNA Polymerase II because it is responsible for transcription of mRNA 7. No, this is not epigenetic inheritance because the alteration in gene expression is due to a mutation in the DNA sequence. Epigenetic inheritance has a phenotypic difference without a DNA sequence modification. 8. A reporter gene is a gene that can be inserted into a sequence to replace a gene of interest you would like to study and measure the level of expression of that gene of interest. Firefly luciferase is often used as a reporter gene because when the protein is translated, it glows and therefore is easy to observe and measure, which relates to the amount of gene expression of the gene of interest as well. 9. A. A small amount of RLUs will be generated (&lt;10,000 RLUs) because the TATA box is not required for transcription, it only enhances the rate of transcription....
