16: Prokaryotes (part 1) Quizellenjmchenry2022-11-23T14:03:43-05:00 Please sign up for the course before taking this quiz. 1. In addition to genomic DNA, bacteria often have “bonus” circlets of DNA known as1 spools. RNA rings. plasmids. peptidoglycan. 2. What is FALSE about prokaryotes?1 They have ribosomes. They can have cell walls. They do not have DNA. They do not have a nucleus. 3. What does penicillin do in bacteria?1 Prevents the process of conjugation. Interferes with protein translation on the bacterial ribosome. Interferes with the enzyme that crosslinks the peptidoglycan cell wall. Interferes with the bacteria's ability to uptake and utilize the amino acid alanine. 4. What is commonly found encoded on a plasmid?1 Enzymes for how to make ribosomes An exact copy of the genomic DNA Antibiotic resistance Ability to form a nucleus 5. Archae bacteria are different from other bacteria because1 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. they do not live on the human body. 6. Bacterial cell walls are made of peptidoglycan, which is a word that means1 "before" a "nut or kernel" "old" "proteins" "outside" "wall" "protein" "sugar" 7. Which of the bacteria shapes look like spheres?1 spirilli bacilli vibrio cocci 8. Which of these is NOT a function of the pili?1 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. Help bacteria to stay attached to surfaces. 9. Which of these cell parts do bacteria NOT have? (select 1)1 Cytoplasm Nucleus Ribosomes Cell wall Cytoskeleton Plasma membrane Vesicles and vacuoles 10. You have more bacteria cells in and on your body than your own.1 True False 15: How proteins are made (part 3: Transcription) 17: Prokaryotes (part 2) Back to: 16: Prokaryotes (part 1)
