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