They both eventually cause death to the host cell.
The lysogenic pathway includes integration into the host cell DNA, replication during fission, and a period of dormancy. The lytic pathway proceeds rapidly. The virus attaches and penetrates the host; viral DNA directs synthesis and replication; new viral particles are assembled and cuse the host cell to lysis. The infectious particles are quickly released into the host.

How are lysogenic and lytic cycles different?
the lytic cycle causes disease apex 2.1.6 During the iysogenic cycle, the cell is not killed
Describe what happens to the host cell of a lysogenic virus?
In the lysogenic cycle, the viral DNA or RNA enters the cell and integrates into the host DNA as a new set of genes called prophage. That is, the viral DNA becomes part of the cell's genetic material. It does not destroy the host cell.
In the lytic cycle the host cell?
In the lysogenic cycle, the viral DNA or RNA enters the cell and integrates into the host DNA as a new set of genes called prophage. That is, the viral DNA becomes part of the cell's genetic material. It does not destroy the host cell.
What happens first when a phage infects a bacterial cell and is going to enter a lysogenic cycle?
it becomes a part of the bacterial DNA and it can be replicated into the daughter cells. this cycle doesn't harm the bacterial cell but it can change into the lysis cycle and kill the host cell
Do viruses replicate by binary fission?
No. The construction of a virus takes place inside of a host cell. The virus is 'not involved' in its own reproduction (in a manner of speaking). Viruses do not reproduce as cells do. A virus operates by injecting its genetic material and sometimes accompanying enzymes into a cell. It then essentially hijacks the cell and forces it to create more of the virus, usually killing the cell in the process.
Does Measles go through the lysogenic life cycle or lytic life cycle?
tuberculosis is caused by a bacterium. lytic and lysogeinc cycles are a part of viral life-cycle.
When a virus takes over a cell what part of the virus takes over the cells functions?
The easiest way to understand how viruses replicate is to study the life cycles of viruses called bacteriophages (bacteria eaters). Bacteriophages replicate by either a lytic cycle or a lysogenic cycle. The difference in these two cycles is that the cell dies at the end of the lytic cycle or the cell remains in the lysogenic cycle. The virus remains "hidden".
During the lysogenic cycle is a provirus part of a host cell's chromosome?
Yes

What does it mean for a virus to have a lysogenic reproductive cycle?
The lysogenic cycle replicates the phage genome without destroying the host. Similar to Lytic reproduction, Lysogenic also begins when the phage inserts its DNA or RNA into the host cell through its surface. Once the nucleic acid is inside the cell, it forms a circle, and becomes a part of the genome of the host cell. It does this through genetic recombination, or crossing over. Once it joins the host’s genome, it is called a prophage. Since it is a part of the host cell’s genome, the phage’s genetic information is copied and distributed to the daughter cells of the host cell, which continues dividing naturally. This allows the prophage to be repeatedly copied and passed on without destroying the host cell it depends on for metabolic and reproduction purposes. In order for actual active phages to be produced, the segment of genome from the original phage exits the genome of the host cell and becomes independent. When this occurs, it begins the lytic cycle, destroying the cell, but producing new and functional phages.

What is lytic infection?
On an x-ray, lytic lesions are light areas found in otherwise dense bone. This suggests something has destroyed or replaced that part of bone. There are both cancerous and noncancerous causes of lytic lesions.

What happends when a bacteriophage infects a bacterial cell?
The phage injects it's genetic material into the bacteria this can either be RNA, DNA or both. This genetic material is then translated into viral proteins which are assembled into new viruses along with a brand new genetic package ready to infect a new bacteria.
Which virus enters a cell and the virus's genetic material becomes part of the cell?
This is something all viruses do in effect when they attack a cell and make the cell start producing new viruses as a part of their reproductive process. See the related question below about the Lytic Cycle which describes the steps in that process.
