16: Prokaryotes (part 1) Quizellenjmchenry2021-10-01T23:30:11-04:00 Please sign up for the course before taking this quiz. What is FALSE about prokaryotes?1 They can have cell walls. They do not have DNA. They do not have a nucleus. They have ribosomes. In addition to genomic DNA, bacteria often have “bonus” circlets of DNA known as1 plasmids. RNA rings. peptidoglycan. spools. Archae bacteria are different from other bacteria because1 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. they do not have a nucleus. Which of these cell parts do bacteria NOT have? (select 1)1 Nucleus Vesicles and vacuoles Plasma membrane Cytoplasm Cell wall Ribosomes Cytoskeleton 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. What does penicillin do in bacteria?1 Prevents the process of conjugation. 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. What is commonly found encoded on a plasmid?1 Ability to form a nucleus Antibiotic resistance An exact copy of the genomic DNA Enzymes for how to make ribosomes Which of the bacteria shapes look like spheres?1 cocci spirilli bacilli vibrio You have more bacteria cells in and on your body than your own.1 True False Bacterial cell walls are made of peptidoglycan, which is a word that means1 "before" a "nut or kernel" "old" "proteins" "protein" "sugar" "outside" "wall" 15: How proteins are made (part 3: Transcription) 17: Prokaryotes (part 2) Back to: 16: Prokaryotes (part 1)
