What does a ribosome do?1 duplicates DNA dissolves proteins assembles virus parts makes proteins Bactetiophages can slowly walk using their “legs” (tail fibers).1 True False What disease does “Yersinia pestis” bacteria cause?1 yellow fever dystenery Bubonic plague typhus cholera The lytic cycle allows the virus to hide for a long time.1 True False What is the function of a phage’s tail fibers?1 To let it walk around. To poke holes in the surface of the bacteria. To attach to a receptor on the surface of the bacteria. To inject the DNA. How fast can a bacteriophage do its entire replication process inside a cell?1 24 hours 30 minutes 3 hours 30 seconds Some enzymes can dissolve (break apart) proteins.1 True False What does “morphology” refer to?1 size shape change classification Which of these diseases did d’Herelle not try to cure with phages?1 yellow fever plague cholera dystentery typhus What type of bacteria does T4 attack?1 Dysentery Typhus Coccobacillus E. coli Yersinia pestis Which one of these is NOT a bacteria part?1 endoplasmic reticulum ribosome cytoskeleton nucleoid membrane Viral DNA is not the same as bacterial DNA.1 True False Every living cell is surrounded by at least one membrane made of lipids.1 True False Which one of these is NOT a viral part?1 membrane DNA collar capsid tail Which continent did d”Herelle never visit?1 Antarctica South America Africa North America Asia VIRUSES lesson 3: History of discovery VIRUSES lesson 5: How Viruses Enter Cells Back to: VIRUSES lesson 4: Bacteriophages
