16: Prokaryotes (part 1) Quizellenjmchenry2021-10-01T23:30:11-04:00 Please sign up for the course before taking this quiz. What is commonly found encoded on a plasmid?1 Enzymes for how to make ribosomes An exact copy of the genomic DNA Ability to form a nucleus Antibiotic resistance Which of the bacteria shapes look like spheres?1 vibrio spirilli bacilli cocci Which of these cell parts do bacteria NOT have? (select 1)1 Nucleus Ribosomes Vesicles and vacuoles Cell wall Plasma membrane Cytoskeleton Cytoplasm What is FALSE about prokaryotes?1 They can have cell walls. They do not have a nucleus. They have ribosomes. They do not have DNA. Which of these is NOT a function of the pili?1 Bacteria use them like grappling hooks to hold or grab onto something. Used in conjugation to transfer a plasmid to another bacteria. Help bacteria to stay attached to surfaces. Used by ribosomes in the process of protein translation. Archae bacteria are different from other bacteria because1 they do not have a nucleus. they do not live on the human body. they do not have DNA but are rather RNA organisms. their DNA is wound on spools similar eukaryotes (animals, plants, etc.) Bacterial cell walls are made of peptidoglycan, which is a word that means1 "protein" "sugar" "outside" "wall" "before" a "nut or kernel" "old" "proteins" 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 the enzyme that crosslinks the peptidoglycan cell wall. Interferes with protein translation on the bacterial ribosome. In addition to genomic DNA, bacteria often have “bonus” circlets of DNA known as1 peptidoglycan. spools. RNA rings. plasmids. You have more bacteria cells in and on your body than your own.1 True False 15: How proteins are made (part 3: Transcription) 17: Prokaryotes (part 2) Back to: 16: Prokaryotes (part 1)
