Molecular Biology of the Cell 6th Edition Alberts Test Bank MOLECULAR BIOLOGY OF THE CELL, SIXTH EDITION CHAPTER 1: CELLS AND GENOMES 1. Scientists discover more than ten thousand new species of living organisms every year. What is shared between all of these organisms? A. They are made of cells, whose nuclei enclose their DNA. B. They obtain their energy from sunlight. C. They produce and use adenosine triphosphate (ATP). D. Their genome contains at least 1000 genes. E. All of the above. 2. All cells … A. have membrane transport proteins. B. synthesize proteins on the ribosome. C. replicate their genome by DNA polymerization. D. transcribe their genetic information by RNA polymerization. E. All of the above. 3. Imagine a segment of DNA (within a gene) encoding a certain amount of information in its nucleotide sequence. When this segment is fully transcribed into mRNA and then translated into protein, in general, … A. the protein sequence would carry more information compared to the DNA and mRNA sequences, because its alphabet has 20 letters. B. the protein sequence would carry less information compared to the DNA and mRNA sequences, because several codons can correspond to one amino acid. C. the amount of information in the mRNA sequence is lower, because the mRNA has been transcribed using only one of the DNA strands as the template. D. the amount of information in the mRNA sequence is higher, because several mRNA molecules can be transcribed from one DNA molecule. 4. Which of the following processes that happens inside a cell DOES NOT normally require consu mption of free energy by the cell? A. Replication of the genetic material B. Import of nutrients from the environment C. Diffusion of small molecules within the cell D. Regulation of gene expression E. Synthesis of enzymes that catalyze cellular reactions 5. Which of the following would you NOT expect to find in a bacterial cell? A. Swimming using flagella B. Having a cell wall around the plasma membrane C. ATP production in mitochondria D. Protein production on the ribosome E. Sexual exchange of DNA with other bacteria 6. To trace family relationships between distantly related organisms such as humans, algae, bacteria, and archaea, one should compare their genomes in regions … A. that evolve rapidly. B. that have a higher mutation rate. C. that code for proteins. D. where mutations are hardly tolerated. E. where most mutations are selectively neutral. 7. Laboratory strains of the model organism Escherichia coli that are resistant to antibiotics are very often used in research laboratories as well as in the biotechnology industry. If cultures of such bacteria were allowed to contaminate the environment uncontrollably, it is possible that at some point, pathogenic bacteria such as Neisseria meningitidis (which causes meningitis and can cause death, especially in children) could acquire the same antibiotic -resistance gene, causing a meningitis outbreak that is difficult to treat. In this scenario, which of the following mechanisms is a more likely source of the antibiotic -resistance gene in N. meningitidis ? A. Random new gene generation B. Intragenic mutation C. Gene duplication D. DNA segment shuffling E. Horizontal gene transfer 8. A virus … A. is a type of cell. B. has genetic material made of proteins. C. can only infect a single host species. D. can act as a vector for gene transfer. E. cannot persist in its host for more than one cell generation. 9. Which of the following does NOT typically involve horizontal gene transfer? A. Sexual reproduction in humans B. Bacteriophage infection of bacteria C. The evolutionary history of the eukaryotic cell D. The accidental duplication of a small region of a bacterial chromosome followed by cell division E. Introduction of plasmids into bacteria in a laboratory 10. Gene duplication can give rise to homologous genes that are part of gene families. For example, there are six actin genes in the genome of most mammalian species. In humans, the ACTB gene, which encodes a cytoskeletal actin, is expressed ubiquitously, while ACTC1 is expressed mainly in cardiac cells. Although bacteria lack the eukaryotic cytoskeletal organization, the bacterial MreB gene bears recognizable sequence similarity to mammalian actin genes and codes for a protein that is similar to actin in structure and function. Which of the following statements is true about these genes? A. ACTB is homologous to ACTC1 but not to MreB . B. ACTB is orthologous to ACTC1 but not to MreB . C. ACTB is paralogous to ACTC1 but not to MreB . D. MreB is orthologous to ACTB but not to ACTC1 . E. ACTB is paralogous to both ACTC1 and MreB . 11. Out of nearly 5000 protein -coding gene families, there is a set of nearly 300 conserved gene families that are found in species from all domains of life. When one looks at the general functions assigned to these gene families, it is found that … A. the majori ty of them function in cell-to-cell signaling. B. the majority of them are poorly characterized. C. more than one-third of them are involved in translation or amino acid transport and metabolism. D. more than one-half of the shared families are involved in DNA replication and transcription. E. Nearly all of them are involved in energy production and carbohydrate metabolism. 12. Which of the following is true regarding Escherichia coli ? A. Most of our understanding about mitosis comes from studies on this model organism. B. It is a rod-shaped bacterium that can only grow in the gut of humans and other vertebrates. C. Two strains of E. coli can differ by up to 0.1% in their genomes. D. E. coli strain K -12 encodes about 4300 proteins. E. The E. coli (strain K -12) genome is about 430 million nucleotide pairs long. 13. Which of the following is NOT true regarding the tree of life? A. Most bacteria and archaea have 1000 to 6000 genes in their genomes. B. Eukaryotes are more similar to archaea than to bacteria with respect to the proteins that act on their DNA. C. Most bacteria and archaea have genome sizes between one and ten million nucleotide pairs, whereas eukaryotic genomes can be millions of times larger. D. Archaeal species were thought to belong to the eukaryotic world before sequence analysis placed them in a separate domain of life. E. Photosynthetic bacteria are thought to be the ancestors of the eukaryotic chloroplasts. 14. A mutation in the cdc28 gene in the budding yeast Saccharomyces cerevisiae causes cell - cycle arrest, giving rise to unbudded cells that look like “dumbbells.” Treatment of wild -type cells with nocodazole, a drug that destabilizes some cytoskeletal polymers, leads to a similar phenotype. Based only on these observations, which statement is true regarding cdc28 ? A. cdc28 codes for a master regulatory kinase that phosphorylates other proteins. B. Nocodazole binds to the protein coded by the cdc28 gene. C. The product of the cdc28 gene is responsible for resistance to nocodazole. D. The product of the cdc28 gene is involved in cell cycle regulation. E. The product of cdc28 destabilizes the same cytoskeletal polymers that nocodazole also destabilizes. 15. Which of the following structures is exclusively found in eukaryotic cells? A. Plasma membrane B. Cell wall C. Chromosome D. Ribosome E. Lysosome
