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