Shown below is the structure of a Drosophila gene, divided into 10 segments, designated A-J. The gene contains three exons, two introns, a promoter, and a site in I for poly(A) addition. a) What segment or segments of the gene will be fully represented in the initial RNA transcript? List the appropriate letter or letters. B) What segment or segments of the gene will be fully represented in the completely processed transcript? c) What segment or segments of the gene in the processed transcript will have additional nucleotides added to them? d) What segment or segments of the gene contain the CCAAT box and TATA box elements? e) What segment or segments of the gene will possess the translation initiation codon? A number of mutations affect the expression of the lactose operon in E.coli. Complete the table given below. Use + to indicate that the enzyme is synthesized at greater than basal levels, and to indicate that enzyme is not synthesized.
