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