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