Unformatted text preview: PHASES OF PHAGE GROWTH a. Latent period--number of plaque-forming units (viruses) remains constant. Phages are invading host cells and causing the synthesis of viral proteins and the replication of the nucleic acid, but no now virions are been released. b. Eclipse period--first part of the latent perio, when no new virions have been produced. c. Rise period--great increase in the number of plaque-forming units as cells are lysed and new virions are released. This phase continues until all of the bacteria have been invaded and lysed. d. Burst size--number of phages released per cell. 2. Lysogenic cycle---also known as lsyogeny. Some viruses do not always cause lysis and death of the host cell right away. Some are able to undergo a cycle in which they integrate their DNA into the chromosome of the host cell. Phages that behave this way are called lysogenic, avirulent, into the chromosome of the host cell....
