In the lytic cycle the virus destroys the cells DNA and with its own genetic material hijacks the cellular machinery to make its own proteins and genetic material. In the lysogenic cycle the virus inserts its own genetic material into the cells DNA and passes this down many reproductive cycles until the multiplicity of infected cells reach a point where the lytic cycle proceeds.

What do you call that a virus invades?
A virus which invades a cell can be said to be virulent. One that causes the host cell to immediately produce virus' particles and lose it's ability to live is said to be a lytic virus. A virus that remains "silent" for awhile is called a lysogenic virus.
A virus that kills its host is said to be?
A virus that kills its host is said to be virulent. Virulent viruses can cause serious illness or death in their host organisms.
What is the difference between lytice cycle and lysogenic cycle?
The lysogenic cycle incorporates its DNA into the cells DNA, lets the cell resume normal growth by reproduction, so that all the cells have viral DNA and lyse to produce more viruses than ever. The lyctic cycle merely infects and lyses one cell at a time.
What do enveloped viruses possess?
As the virus is leaving the cell (budding), it sometimes takes along a part of the cell's membrane called the envelope. Those viruses without an envelope are called "naked" viruses. Those with one are said to be enveloped.
Can a virus replicate outside a living cell?
What we need to understand is, viruses do not have its own synthetic machinery such as ribosomes to make proteins. Hence they are completely dependent on the host synthetic machinery for their replication. Virus infects the host cells, integrate its genetic material with the host to produce progeny viral particles.
Why virus are called obligatory parasites?
They are obligate in the sense that they cannot replicate outside of a host cell. To make a copy of itself, a virus must first enter a cell (intracellular), hijack the machinations of said cell (parasitic behavior) and then copy itself.
Why is the unicellular organism virus said to be the smallest organism eve though bacterial cell is the smallest cell?
FU
What is a virus called which enters a cell and remains inactive for long periods of time?
A virus that remains inactive for a time is said to be lysogenic.
How viruses survive outside the host cell?
they don't - unless it has divided itself into another cell viruses are not taken as the living entities.....they are said to be on border line of living and non living and are more accurately accepted as chemical in nature as they can be crystallised unlike living cells......they don't abide by the standards of being living expecting the fact that they replicate in their host cell. thus they can't be said to b surviving outasice host cell....or they need not to survive.
What does it mean when a virus can sleep?
When a virus is said to "sleep," it typically refers to its ability to enter a dormant state, often called latency. In this state, the virus is not actively replicating or causing disease, but it can remain in the host's cells without being detected by the immune system. This dormancy allows the virus to evade the host's defenses and can reactivate later, potentially causing infection again. This behavior is commonly seen in certain viruses, such as herpesviruses.
Why does a certain virus attach to only one type or few types of cells?
Yes. According to Pearson Education's book, "Each virus contains unique proteins on its outer surface. The shape of these proteins allows the virus to attach to, or lock onto, only certain host cells."
Why are viruses non-living?
They are not alive. They are nonliving. They are like cockle burrs that "grab" hold of your clothing or a dog's coat. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These parts can assemble into more viruses and then they break out of the cell (killing it) and begin the process again. They cannot make more viruses on their own.
