16: Prokaryotes (part 1) Quizellenj2022-11-23T14:03:43-05:00 Please sign up for the course before taking this quiz. 1. You have more bacteria cells in and on your body than your own.1 True False 2. Bacterial cell walls are made of peptidoglycan, which is a word that means1 "old" "proteins" "protein" "sugar" "before" a "nut or kernel" "outside" "wall" 3. What is FALSE about prokaryotes?1 They have ribosomes. They do not have a nucleus. They do not have DNA. They can have cell walls. 4. Archae bacteria are different from other bacteria because1 they do not have a nucleus. they do not have DNA but are rather RNA organisms. they do not live on the human body. their DNA is wound on spools similar eukaryotes (animals, plants, etc.) 5. Which of these cell parts do bacteria NOT have? (select 1)1 Vesicles and vacuoles Cytoskeleton Ribosomes Plasma membrane Cytoplasm Cell wall Nucleus 6. What does penicillin do in bacteria?1 Prevents the process of conjugation. Interferes with protein translation on the bacterial ribosome. Interferes with the enzyme that crosslinks the peptidoglycan cell wall. Interferes with the bacteria's ability to uptake and utilize the amino acid alanine. 7. What is commonly found encoded on a plasmid?1 Antibiotic resistance Enzymes for how to make ribosomes Ability to form a nucleus An exact copy of the genomic DNA 8. Which of these is NOT a function of the pili?1 Used in conjugation to transfer a plasmid to another bacteria. Help bacteria to stay attached to surfaces. Bacteria use them like grappling hooks to hold or grab onto something. Used by ribosomes in the process of protein translation. 9. Which of the bacteria shapes look like spheres?1 cocci spirilli bacilli vibrio 10. In addition to genomic DNA, bacteria often have “bonus” circlets of DNA known as1 spools. plasmids. peptidoglycan. RNA rings. 15: How proteins are made (part 3: Transcription) 17: Prokaryotes (part 2) Back to: 16: Prokaryotes (part 1)
