Which of the following statements about the study and nature of viruses is NOT true? Question 17Select one: Bacteriophages are viruses that infect all living cells but only lyse bacteria. Viruses make use of the biosynthetic machinery of infected cells in order to reproduce. Early work using filters demonstrated that viruses are smaller than cells, but only by using later techniques such as electron microscopy were researchers able to visualize viruses. Viruses do not comply with Koch’s second postulate, one of the criteria used to identify disease-causing pathogens. The culture of viruses requires living cells in an appropriate culture medium.
