A) bacteriophages B) proviruses C) lytic phages D) retroviruses E) viroids 2) RNA viruses require their own supply of certain enzymes because A) host cells rapidly destroy the viruses. B) these enzymes cannot be made in host cells. C) these enzymes translate viral mRNA into proteins. D) host cells lack enzymes that can replicate the viral genome. E) these enzymes penetrate host cell membranes. 2) RNA viruses require their own supply of certain enzymes because A) host cells rapidly destroy the viruses. B) these enzymes cannot be made in host cells. C) these enzymes translate viral mRNA into proteins. D) host cells lack enzymes that can replicate the viral genome. E) these enzymes penetrate host cell membranes. 3) Which of the following statements describes the lysogenic cycle of lambda ( λ ) phage? A) Most of the prophage genes are activated by the product of a particular prophage gene. B) The phage genome replicates along with the host genome. C) Certain environmental triggers can cause the phage to exit the host genome, switching from the lytic to the lysogenic. D) The phage DNA is incorporated by crossing over into any nonspecific site on the host cell's DNA. E) After infection, the viral genes immediately turn the host cell into a lambda-producing factory, and the host cell then lyses. 3) Which of the following statements describes the lysogenic cycle of lambda ( λ ) phage? A) Most of the prophage genes are activated by the product of a particular prophage gene....
