Lecture 33 Study Guide 1. Compare the effect on the host cell of the lytic cycle versus the lysogenic cycle. A phage reproductive cycle that culminates in death of the host cell is known as the lytic cycle . (A type of viral phage replication cycle resulting in the release of new phages by lysis and death of the host cell.) The lysogenic cycle replicates the phage genome without destroying the host. (A phage replication cycle in which the viral genome becomes incorporated into the bacterial host chromosome as a prophage and does not kill the host. (338) 2. Bacterial reproduction is primarily by binary fission which is a duplication division from a single cell. How does genetic diversity occur in bacterial cells that just undergo binary fission? Mutation can cause some of the offspring to differ slightly in genetic makeup. Even in bacteria, where new mutations are a major source of individual variation, additional diversity arises from genetic recombination, defined as the combining of DNA from two sources. In most of the cases we discuss here, the two sources
