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. 3. Bacterial cell walls are made of peptidoglycan, which is a word that means1 "old" "proteins" "protein" "sugar" "before" a "nut or kernel" "outside" "wall" 4. Which of the bacteria shapes look like spheres?1 vibrio bacilli spirilli cocci 5. In addition to genomic DNA, bacteria often have “bonus” circlets of DNA known as1 plasmids. spools. peptidoglycan. RNA rings. 6. What is commonly found encoded on a plasmid?1 Enzymes for how to make ribosomes Antibiotic resistance Ability to form a nucleus An exact copy of the genomic DNA 7. What is FALSE about prokaryotes?1 They do not have DNA. They have ribosomes. They can have cell walls. They do not have a nucleus. 8. What does penicillin do in bacteria?1 Interferes with the bacteria's ability to uptake and utilize the amino acid alanine. Interferes with protein translation on the bacterial ribosome. Prevents the process of conjugation. Interferes with the enzyme that crosslinks the peptidoglycan cell wall. 9. Archae bacteria are different from other bacteria because1 their DNA is wound on spools similar eukaryotes (animals, plants, etc.) they do not have DNA but are rather RNA organisms. they do not live on the human body. they do not have a nucleus. 10. Which of these cell parts do bacteria NOT have? (select 1)1 Ribosomes Plasma membrane Cytoskeleton Vesicles and vacuoles Cytoplasm Cell wall Nucleus 15: How proteins are made (part 3: Transcription) 17: Prokaryotes (part 2) Back to: 16: Prokaryotes (part 1)
