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