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