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 have ribosomes. They do not have DNA. They do not have a nucleus. They can have cell walls. 2. Bacterial cell walls are made of peptidoglycan, which is a word that means1 "protein" "sugar" "outside" "wall" "old" "proteins" "before" a "nut or kernel" 3. What is commonly found encoded on a plasmid?1 Enzymes for how to make ribosomes Antibiotic resistance An exact copy of the genomic DNA Ability to form a nucleus 4. Which of these is NOT a function of the pili?1 Used in conjugation to transfer a plasmid to another bacteria. Used by ribosomes in the process of protein translation. Help bacteria to stay attached to surfaces. Bacteria use them like grappling hooks to hold or grab onto something. 5. Which of the bacteria shapes look like spheres?1 spirilli vibrio cocci bacilli 6. You have more bacteria cells in and on your body than your own.1 True False 7. What does penicillin do in bacteria?1 Interferes with protein translation on the bacterial ribosome. 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. 8. Archae bacteria are different from other bacteria because1 their DNA is wound on spools similar eukaryotes (animals, plants, etc.) they do not live on the human body. they do not have a nucleus. they do not have DNA but are rather RNA organisms. 9. Which of these cell parts do bacteria NOT have? (select 1)1 Ribosomes Vesicles and vacuoles Plasma membrane Cytoplasm Cytoskeleton Nucleus Cell wall 10. In addition to genomic DNA, bacteria often have “bonus” circlets of DNA known as1 peptidoglycan. spools. RNA rings. plasmids. 15: How proteins are made (part 3: Transcription) 17: Prokaryotes (part 2) Back to: 16: Prokaryotes (part 1)
