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