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