You have transformed a common laboratory strain of Escherichia coli (which does not naturally grow on sucrose) with the plasmid pCrazy45, whose map is provided in the image below. This map displays all functional components of the complete vector. The transformation mixture (after a 1-hour recovery in LB broth) was subsequently plated onto different agar media. Consider a specific plate consisting of LB medium supplemented with 5% sucrose and no antibiotics. (a) (3 points) What is the biological function of the enzyme encoded by the SacB gene, as shown on the pCrazy45 map? (b) (7 points) Based only on the functional components of the pCrazy45 plasmid map and the composition of the specific selective agar medium, what would be the expected result for any E. coli cells that were successfully transformed and are now carrying this functional plasmid, if they are plated onto the LB sucrose 5% plate? Explain your answer with clear reasoning.

Lindsаy, а lаwyer, and Andrea, an accоuntant shared оffice space in a building but оtherwise are independent practitioners. Each has a secretary, both of whom work in a common reception room, and each practitioner has her own private office. Willy, a window washer employed by building management, was on a scaffold, washing the window of Andrea’s office, and saw what looked like illegal drugs and drug paraphernalia in an open cabinet in the office. During his lunch break, Willy reported his findings to Patrick, a police officer, and brought Patrick up on the scaffold to look into the office through the window. After observing the items in the cabinet, Patrick entered the reception room and asked Lindsay’s secretary if she worked there. The secretary said that she worked for Lindsay. Patrick asked the secretary for permission to look in Andrea’s office. The secretary agreed, and Patrick seized the drug-related contents of the cabinet. Andrea has been charged with illegal possession of cocaine. Prior to trial, Andrea brings a motion to suppress the evidence of the drugs and paraphernalia. How should the judge rule?
Jаsоn wаs аrrested fоr and charged with armed rоbbery. Police scheduled a lineup identification procedure. Jason’s attorney arrived at the station before the scheduled lineup and was told to wait in the lobby. Inside the lineup room, the six members of the lineup, including Jason, stood on one side of the one-way mirror in full view of the witnesses gathered on the other side in the viewing area. The lineup members stepped forward one by one for a closer inspection. After the first two lineup members had been presented, an officer realized that Jason’s attorney was not present and immediately escorted him to the viewing area. Jason’s attorney arrived in time to witness the presentation of Jason and the remaining three members of the lineup. Two witnesses then identified Jason as the robber. At trial, if the defense objects to the introduction of the lineup evidence, should the objection be granted?
