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