What is the function of the viral glycoproteins that are present in an enveloped virus? A) They are used for entry into new host cells B) They are used to direct the synthesis of viral DNA C) They are the packaging tools for viruses D) They make toxins and make host bacteria pathogenic 3. Which of the following characteristics determine a virus's host range? A) B) C) D) the enzymes carried by the virus whether its nucleic acid is DNA or RNA the proteins on its surface and that of the host the proteins in the host's cytoplasm 4. What is the function of reverse transcriptase in retroviruses? A) It hydrolyzes the host cell's DNA B) It uses viral RNA as a template for DNA synthesis. C) It converts host cell RNA into viral DNA. D) It uses viral RNA as a template for making complementary RNA strands. 5. Which of the following statements correctly describes the lysogenic cycle of lambda (0) phage? A) After infection, the viral genes immediately turn the host cell into a lambda-producing factory. and the host cell then lyses. B) The phage genome is degraded and cut into small pieces C) The phage genome replicates along with the host genome. D) Certain environmental triggers can cause the phage to exit the host genome, switching from t lytic to the lysogenic.
