Detailed explanation-1: -Lytic infection involves the replication of a viral genome. This genome is packaged into a viral coat and released from the cell. This process of viral release from the cells results in lysis of cells, and hence, it is termed the ‘lytic phase’.
Detailed explanation-2: -The lytic cycle leads to the death of the host, whereas the lysogenic cycle leads to integration of phage into the host genome. Bacteriophages inject DNA into the host cell, whereas animal viruses enter by endocytosis or membrane fusion. Animal viruses can undergo latency, similar to lysogeny for a bacteriophage.
Detailed explanation-3: -The lytic cycle is named for the process of lysis, which occurs when a virus has infected a cell, replicated new virus particles, and bursts through the cell membrane. This releases the new virions, or virus complexes, so they can infect more cells.
Detailed explanation-4: -In the lytic cycle, the phage replicates and lyses the host cell. The third stage of infection is biosynthesis of new viral components.
