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