There are 10 pages including the cover and scoring pages, and 40 questions. Please make sure that you have all of the pages before you start working on the examination. 2. Please write your name at the top of this page now. 3. Read each question carefully before you start to answer it. If you have questions about the exam, ask! Regrade policy: 1. If you feel that a question has not been graded correctly, return the entire exam within one week to Professor Cushman. Attach a note about the error. Professor Cushman will regrade the entire examination. This means you could either gain or lose total points. 2. If there is an error in addition of points, return the exam with a note to that effect. The examination will be totaled correctly without regrading the entire exam. 2 Scoring Page (20) 1-10 ______ (20) 11-20 ______ (30) 21-30 ______ (30) 31-40 ______ Total ______ 3 Matching (2 points each) (20 total points) O O CH 3 OH H 3 C OH HO H 3 C CH 3 CH 3 O H 3 C O O H 3 C O O CH 3 OH OCH 3 OH OH CH 3 N H 3 C CH 3 OH O CH 3 HO OH O NH 2 O N(CH 3 ) 2 H OH H OH O 2 N OH OH HN O CHCl 2 O O HN O N H H N O N H H N O O O O NH 2 O N H O CH 3 CH 3 NHCH 3 OH OH OH HO HO Cl O OH HO OH O O HO H 3 C NH 2 CH 3 Cl CO 2 H A B C D O HO HO O HO H 2 N NH 2 O O H 2 N OH HO HO NH 2 HO E N O N O NH CH 3 O O F H 2 N S O O N H O N H 3 C CH 3 N O CO 2 H N F HN O F G H J O H N O N N S N O N HN NH O O O N O O O N OH I Please match the statement below with the letter of the structure of the drug above. 1 __ C __ Inhibits translocation of peptidyl-tRNA from the A site to the P site of the ribosome.
