covalent bond E They will form a nonpolar covalent bond 3 Nitrogen has atomic number of 7 and Neon the noble gas in the same row of the periodic table has an atomic number of 10 From this information

amp C above 7 Biological polymers are disassembled by A Oxidation reactions B Reduction reactions C Dehydration reactions DHydrolysis reactions E A chain saw 8 In considering polymers of glucose that

because they are both made by plants C Starch and cellulose are most similar in terms of function because they are both made by animals D Starch and glycogen are most similar in terms of function

group B an NHz group C H Dall of the above B only A amp B above 10 Polypeptides and polynucleotides are similar in that each A is composed of two antiparallel strands B forms a helix in solution C has

be commonly found in plants C is solid at room temperature Dboth A amp B above E both A amp C above 12 The plasma membrane of a cell is composed of A a phospholipid bilayer with associated proteins B a phospholipid monolayer with associated proteins C a pure phospholipid bilayer D a layer of protein and a layer of phospholipid that together form a bilayer E alternating layers of protein and phospholipid the amount depending on the type of cell 13 Every cell on this planet has A a plasma membrane B DNA as genetic material C endoplasmic reticulum D all of the above E only A amp B above 14 The role of the Golgi apparatus in the cell is A detoxifying foreign substances B protein synthesis especially membrane proteins C sorting and modifying proteins D storage and expression of genetic information E as the site of energy metabolism 15 The cytoskeleton is composed of A three different proteins that form different structural and functional elements B actin filaments microtubules and cellulose fibers C a mixture of carbohydrate and protein to form three different functional and structural elements D elements that include a mixture of each of the important biopolymers E a mixture of bailing wire and duct tape 16 The smooth endoplasmic reticulum is important to the cell as A a site of protein synthesis B the site of lipid and membrane synthesis C an organelle involved in detoxification Dboth A amp B E both B amp C 17 You are studying a specific type of tissue in culture out of the body You are investigating the connections between the cells in this tissue and have as a tool a small dye molecule You inject dye into cells in one part of the tissue and find that later the dye has moved into cells far from the original injection site There is also no dye in the solution outside the cells From these data you conclude that the cells A must have tight junctions that prevent the movement of water between the cells B must have gap junctions that allow the diffusion of material between cells C must have adherans junctions that allow the diffusion of materials between cells Dmust have tight junctions that allow the diffusion of materials between cells E must have gap junctions that allow material to move out of one cell then back into another cell 18 Cellular material can move into and out of the nucleus A through nuclear pores that penetrate the double membrane B by simple diffusion through the nuclear envelope C by facilitated diffusion through the proteins in the phospholipid bilayer that makes up the nuclear envelope Dby active transport through the endoplasmic reticulum E by nuclear pores in the Golgi 19 Transport of a molecule like glucose into a cell can occur by A simple diffusion B facilitated diffusion C active transport D all of the above E only B amp C above 20 Active transport and endocytosis are similar in that both A transport a large amount of material at the same time compared to other processes B require energy to move material across the membrane C require a concentration gradient to move materials across the membrane D use transmembrane proteins to move materials across the membrane B only transport hydrophobic substances 21 Transport of an ion by facilitated diffusion requires A an ion channel and energy B a carrier protein and energy C an ion channel and a concentration gradient D only a concentration gradient E a small shortlived hole in the membrane 22 Inspired by watching the Olympics you decide you need to learn how to cross country ski After a long afternoon a companion notices that you are behaving erratically and suggests you are dehydrated After a trip to the ER they prescribe rehydration via IV fluids The nurse assures you that the distilled water solution you are being hooked up to will rehydrate you very quickly You respond that this is a bad idea because distilled water is Ahypotonic relative to blood plasma and will cause your blood cells to shrink B hypotonic relative to blood plasma and will cause your blood cells to swell C hypertonic relative to blood plasma and will cause your blood cells to shrink Dhypertonic relative to blood plasma and will cause your blood cells to swell E isotonic relative to blood plasma and you need a hypertonic solution 23 Nucleotides are composed of A a ribose sugar deoxyribose or ribose B a phosphate group PO4 C nitrogenous bases purines and pyrimidines Dall of the above B an amino group a carboxyl group H and an R group 24 Polynucleotide strands A are composed of alternating sugar and phosphate groups joined

bases and found that the amount of AT and GC The Watson and Crick model rationalizes these data by Awrapping the two strands of the helix about a common axis B arranging the two strands in an antiparallel orientation C base pairing involving specific patterns of hydrogen bonds Dbase pairing involving specific patterns of phosphodiester bonds E the polar nature of the two strands 26 If one strand of DNA has the sequence shown below 5 39 GTCTGAATGCGTACATCA 3 39 Which of the following would be the correct complementary strand Au539 GTCTGAATGCGTACATCA 339 B539 TGATGTACGCATTCAGAC 339 CL539

with each composed of a mixture of old and new strands C two molecules with each composed of one old strand and one new strand D two molecules with each composed of completely new strands E two molecules one that is composed of one old and one new strand and the other with two completely new strands 28 Consider the following statements about DNA replication in cells I All DNA polymerases synthesize new DNA 5 to 3 II The primers synthesized on the lagging strand are made by a special DNA polymerase enzyme called primase III The helicase enzyme acts to unwind the double helix in front of the polymerase AI amp II are true B I amp III are true C II amp III are true DI II amp III are true E none are true 29 The two strands of the double helix are replicated A in the same way at the same time B differently one is synthesized 5 to 3 and the other 3 to 5 C differently one is synthesized continuously and the other is synthesized discontinuously D differently they are synthesized by different kinds of DNA polymerases E at different times during the cell cycle 30 Activities that are necessary on the lagging strand include A a second DNA polymerase to remove and replace RNA primers B primase to synthesize RNA primers C DNA ligase to join together the pieces of new DNA Da11 of the above B only B amp C above 31 Bacterial cell division is a relatively simple process where A the products of replication are glued together with protein B replicated chromosomes are passively segregated by cell growth C cells produce many copies of the chromosome then divide in the middle D DNA replication and chromosome segregation occur together B DNA polymerase replicates the chromosome and microtubules separate the products 32 Eukaryotic cells insure that daughter cells each get a complete set of chromosomes after division by A marking the chromosomes during replication to keep track of them B gluing chromosomes together after replication to later separate together C attaching the products of replication to microtubules that then immediately pull them apart D segregating the chromosomes by pushing them to the poles as they are replicated E making sure the cell is divided exactly in half during cytokinesis 33 The cell cycle can be divided into interphase which includes and M phase which includes A G1 G2 S and M Cytokinesis B G Gzand cytokinesis S and M C G1 G2 and M S
