Solution:

In the lytic cycle, a virus enters a cell and causes it to produce viral nucleic acid and protein coats. After these viral pans are assembled, the new virus panicles may burst from the host cell or may leave the host cell by budding. In the lysogenic cycle, viruses enter into a long-term relationship with the cells they infect, their nucleic add replicating as the cells multiply.
