-1-BIOS 100 - Fall, 2006pm Name:Exam II, 20 Oct, 2006 Michael Muller, Instructor TA:This exam consists of 54 questions over 7 pages. Please check to see that all the pages are present beforeyou begin. Use a #2 pencil and bubble in all answers. If you do not bubble in your last name first, I willremove all extra credit points from your score. Your score will be posted on the UIC Blackboard site assoon as they are in. There is a Codon Chart at the end of the exam. Good Luck! Matching - Use the key below to select the best answers for questions 1 - 8.
