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