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