-1-BIOS 100 - Summer 2007 Name:Exam II, 2 July, 2007Michael Muller, Instructor TA:This exam consists of 52 questions over 7 pages (the codon chart is on page 7). Please check to see thatall the pages are present before you begin. Use a #2 pencil and bubble in all answers. Your score will beposted on the UIC Blackboard site as soon as they are in. No kidding. Good Luck! Matching - Use the key below to select the best answers for questions 1 - 7.

If DNA replication were conservative, which of the below results would you expect for theMeselsen Stahl experiment?A B C D E22. All of the following statements about DNA are true EXCEPT:A. DNA is an anti-parallel double helixB. During typical nucleotide pairing, a pyrimidine pairs with a purineC. DNA can base pair with DNA and with RNAD. DNA is always synthesized in a 3' to 5' directionE. A typical nucleotide will have a phosphate group attached to the 5' carbon of theribose sugar23. Which of the following statements (A-D) about DNA replication is FALSE? If statementsA-D are true, then choose E.A. DNA polymerase III requires a primer to initiate synthesis of DNA, but DNApolymerase I does not (it can start from scratch)B. The leading strand is the strand of the replication fork synthesizing DNA in thedirection of helicase unwindingC. Ligase activity is greater in the lagging strand than the leading strandD. When replicating DNA of a linear chromosome, there will be one stand that is slightlyshorter due to the lack of replacement of the RNA primer by DNA polymerase IE. All of the above statements about DNA replication are TRUEMatching - use the key on the right to answer questions 24 - 2624. This enzyme removes supercoils from DNA A. DNA polymerase I25.
