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