Unformatted text preview: recognized by the protein: ____________________________. 2. (25 pts) Describe/diagram the regulation of the trp operon of E. ` coli. 3. (25 points) Describe and diagram the process which the E. coli bacteriophage fX174 produces new single-stranded chromosomes from the original chromosome which enters the bacterial cell. 4. (25 pts) An E. coli cell is infected by a lambda bacteriophage. Describe (and diagram as necessary)the series of molecular events , which leads to the formation of a lysogenic relationship with the bacterial cell. 5a. (10 pts) How can antisense RNAs be utilized to experimentally regulate gene expression in eukaryotic cells? Why is this often more useful than simply creating a mutant defective in this gene product by traditional means (as generally used for bacterial systems)? 5b. (15 pts) Give (explain/diagram) of where antisense RNAs are used naturally by an organism to regulate gene expression...
