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