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