Lytic and lysogenic are the two different types of viral life cycle. In the lysogenic part of life cycle the virus remain in the latent stage. In this stage, the genetic material of the virus gets attached with the host genetic material and gets replicated with the host genome. This stage is called prophase stage.
In lytic part, the viral gene transcribe and produce viral protein from which new phage particles are formed which do apoptosis of cell and gets released from the cell to infect other cells. So to be able to remain latent in the infected live cell HSV virus should shut down the apoptosis process of the infected cells.
DNA is unzipped by helicase at the origin of replication. There are several origins of replications in eukaryotic DNA replication, while only one in prokaryotic replication.
The Law of Conservation of mass is important because then when performing a chemical reaction scientists can determine about the amount of substance that will be produced.
