The only way viruses can replicate ("reproduce") is to take over the cells of a living host.
The only way viruses can replicate ("reproduce") is to take over the cells of a living host.
A virus doesn't destroy the host cell's DNA. The virus depends on the cell's DNA to keep the cell functioning while the virus reproduces. The viruses that actually kill the cell only destroy the DNA indirectly. Once the structure of the cell is broken up in the process of death the DNA is exposed to the environment and breaks up also. However some viruses keep the cell alive and just bud off of it without killing it. A few viruses actually "hide" in the cell's DNA and get reproduced with it when the cell divides.
Through the process of the "Lytic Cycle" of viral reproduction, in most cases by splitting open the cell to release the newly created replicants of the virus. See the related questions below for more information about the lytic cycle.
A virus can either burst the host cell or cause it to stop working.
It is actually the other way around. A virus destroys a host cell after it has make the replicants of the virus. The cell will split open (lyse) when full of new virions which then get released to infect other cells.
Our immune systems can "destroy" a virus in a cell, but the cell itself does not do that. The immune system makes antibodies that fit the virus perfectly to block the way it would have attached to the cell to infect it. The antibody attaches to the virus to prevent its ability to attach to a cell.
See the related question below about the lytic cycle for more details about virus "reproduction".
Viruses use enzymes to destroy host cells after replication is complete.

DNA replication is necessary as cells constantly divide.
Viruses are like cells except they destroy your immune system and take over your body and kill you.
Viruses carry genetic material that they insert into our cells to make our cells stop doing what they normally do and start reproducing viruses, the genetic material is encoded with the information needed to reproduce that specific virus exactly.

Viruses require host cells, whereas cells provide their own replication mechanisms.
No. Only white blood cells destroys pathogens, such as viruses.
They both destroy the cells that they attack.
Viruses are replication parasites that can do nothing until they take over a living cell. Bacteria are living cells.

DNA Viruses: "The genome replication of most DNA viruses takes place in the [host] cell's nucleus." RNA Viruses: "Replication usually takes place in the cytoplasm." Of course, some viruses will differ from these generalizations.
One thing is that antibiotics cannot kill viruses, as viruses are DNA structures which enter the cells in your body in order to duplicate, however antibiotics cannot enter into the cells, and can therefore not stop the virus.
No. Bacteria are not viruses and can not commander other cells in their replication,which is only simplistic fission.
White blood cells destroy bacteria and viruses found in your body by releasing enzymes and proteins to break down the foreign cells then consuming it.
The only way viruses can replicate is by parasitizing living cells and using the cell's mechanisms to replicate their genetic materials and protein components.

Viruses are composed of protein and DNA. The DNA encodes the protein as well as the DNA for the virus. Viruses depend on host cells because they are incapable of reproducing themselves. They enter the host cell and the viral DNA is inserted into the host DNA. The virus then "hijacks" the host cells replication machinery to make more viral protein and viral DNA.
