Detailed explanation-1: -Lysogeny can change the phenotype, fitness and evolution of the bacterial host cell. In the case of bacterial pathogens, prophages allow the acquisition of new traits such as virulence factors which in turn may improve the host’s fitness.
Detailed explanation-2: -Bacteriophages have a lytic or lysogenic cycle. 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.
Detailed explanation-3: -Lysogeny is characterized by integration of the bacteriophage nucleic acid into the host bacterium’s genome or formation of a circular replicon in the bacterial cytoplasm. In this condition the bacterium continues to live and reproduce normally, while the bacteriophage lies in a dormant state in the host cell.
Detailed explanation-4: -Answer and Explanation: Of the following the one that is characteristic of the lysogenic cycle is, the virus using wholesale enzymes, nucleotides and ribosomes to replicate its DNA and assemble capsules. During the lysogenic cycle, the virus doesn’t lice the cell or destroy the cell.
