MIP 300 Exam I review (CSU) The Cortex - correct answer You develop a drug that inhibits the formation of peptide interridge. You find that it also is effective at stopping sporulation. What part of the spore would you propose this drug is inhibiting formation of? Archaea, Bacteria, Eukarya - correct answer You have isolated a cell that possess the following: 70S ribosomes, double-stranded DNA, and a cytoplasmic membrane composed of a phospholipid bilayer. From this information, into which domain of living organisms would you classify this cell True - correct answer You isolate a microbe that lacks an endoplasmic reticulum. This organism could belong to the Euskara domain. True or false? Exoenzymes - correct answer You perform a gram stain and the bacteria stain purple. Which of the following will be produced by this bacterium Increase - correct answer You grow a mesophilic bacterium in many temperatures. These bacteria take 30 minutes to double at 37 degrees Celsius. If you now put this bacterium ina refrigerator at 4 degrees Celsius, you would expect the doubling time of this bacterium to D - correct answer You are working with a bacterium in the lab that is capable of producing a polysaccharide layer external to the cell wall. You isolate a mutant of this bacterium that can no longer perform this function. Which of the following would you expect to be lacking/reduced in this mutant bacterium A) Ability of bacterium to adhere to host B)Ability to avoid phagocytosis C)The ability to growth and reproduce D)A & B C)A, B, & C A - correct answer You analyze the chemical composition of peptidoglycan from bacteria you isolated from the soil. If the bacterium is Gram negative, which of the following could you find? A)2 types of carbohydrates B)5 different types of amino acids C)a and b D)none of the above E - correct answer Which of the following organisms would you predict can cause joint infections in humans? A)Psychrophilic acidophile B)Mesophilic acidophile C)Thermophiles neutrophile D)Psychrophilic neutrophile E)Mesophilic neutrophile Hot pink because it has a thick cell wall of mycolic acids - correct answer A fellow student is identifying bacteria in lab. They believe they have MycoBacterium tuberculosis, but they are not sure. If they use an acid-fast stain on this organism, how will it appear if they are correct and why? Both 70S and 80S ribosomes - correct answer Yeast cells contain what kind of ribosomes? C - correct answer You are given a bacterium inoculated into a tube of broth with a pH of 3, and you find the generation time is 22 minutes. Which of the following could be the generation time for this same bacterium growing in broth with a pH of 9 if this bacterium is an acidophile: A)15 minutes B)22 minutes C)55 minues D)must be 0 minutes this bacterium cannot reproduce at all in a pH of 9
