16: Prokaryotes (part 1) Quizellenjmchenry2020-07-30T09:07:49-04:00 Please sign up for the course before taking this quiz. What is FALSE about prokaryotes?1 They do not have DNA. They can have cell walls. They do not have a nucleus. They have ribosomes. Which of these cell parts do bacteria NOT have? (select 1)1 Ribosomes Nucleus Cytoplasm Vesicles and vacuoles Cell wall Plasma membrane Cytoskeleton Which of the bacteria shapes look like spheres?1 cocci bacilli spirilli vibrio In addition to genomic DNA, bacteria often have “bonus” circlets of DNA known as1 plasmids. peptidoglycan. spools. RNA rings. 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 You have more bacteria cells in and on your body than your own.1 True False What does penicillin do in bacteria?1 Prevents the process of conjugation. Interferes with protein translation on the bacterial ribosome. Interferes with the bacteria's ability to uptake and utilize the amino acid alanine. Interferes with the enzyme that crosslinks the peptidoglycan cell wall. Archae bacteria are different from other bacteria because1 their DNA is wound on spools similar eukaryotes (animals, plants, etc.) they do not have a nucleus. they do not have DNA but are rather RNA organisms. they do not live on the human body. Bacterial cell walls are made of peptidoglycan, which is a word that means1 "protein" "sugar" "before" a "nut or kernel" "outside" "wall" "old" "proteins" 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. 15: How proteins are made (part 3: Transcription) 17: Prokaryotes (part 2) Back to: 16: Prokaryotes (part 1)
