16: Prokaryotes (part 1) Quizellenjmchenry2022-11-23T14:03:43-05:00 Please sign up for the course before taking this quiz. Which of the bacteria shapes look like spheres?1 vibrio spirilli cocci bacilli You have more bacteria cells in and on your body than your own.1 True False What is commonly found encoded on a plasmid?1 Antibiotic resistance An exact copy of the genomic DNA Ability to form a nucleus Enzymes for how to make ribosomes 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. Archae bacteria are different from other bacteria because1 they do not have DNA but are rather RNA organisms. they do not have a nucleus. they do not live on the human body. their DNA is wound on spools similar eukaryotes (animals, plants, etc.) Which of these cell parts do bacteria NOT have? (select 1)1 Ribosomes Vesicles and vacuoles Cytoskeleton Cytoplasm Plasma membrane Nucleus Cell wall Which of these is NOT a function of the pili?1 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. Bacteria use them like grappling hooks to hold or grab onto something. In addition to genomic DNA, bacteria often have “bonus” circlets of DNA known as1 peptidoglycan. RNA rings. plasmids. spools. 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. Interferes with the bacteria's ability to uptake and utilize the amino acid alanine. Prevents the process of conjugation. Bacterial cell walls are made of peptidoglycan, which is a word that means1 "before" a "nut or kernel" "protein" "sugar" "outside" "wall" "old" "proteins" 15: How proteins are made (part 3: Transcription) 17: Prokaryotes (part 2) Back to: 16: Prokaryotes (part 1)
