Archaebacteria Eubacteria Host cell Tail fibers Virus Binary Fission Plasmid Antibiotics Capsid DNA or RNA Vaccine Complete the table by checking the correct column for each statement. Statement 12. Viral genes are expressed immediately after the virus infects the host cell. 13. Many new viruses are assembled. Lytic Cycle Lysogenic Cycle 14. Viral DNA is passed on to daughter cells during this cycle. 15. Viral DNA is integrated into the host cell’s chromosome. 16. Viruses are released from the host cell by lysis or popping, spreading to other cells in the organism. 17. Host cells DNA is destroyed. Use each of the terms below once to complete the passage. DNA white blood cells Lysogenic Lytic AIDS Many disease-causing viruses have both lytic and 18._________________________ cycles. For example, when HIV infects 19.___________________________________, the virus enters a lysogenic cycle. Their genetic information becomes incorporated into the 20. ___________________________ of the white blood cells, forming protoviruses. When this happens, the white blood cells still function normally, and the person may not appear ill. Eventually, the protoviruses enter a 21. _______________________ cycle, killing the white blood cells. As a result the person loses the ability to fight the diseases and develops 22. ___________.
