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".
The virus's genetic material.
A virus the immediately takes over a cell's functions is an active virus. An active virus causes the host cell to make new viruses, destroying the host cell.
The virus attaches to the outer cell wall,inserts its DNA. It takes the cells functions over and starts a viral factory.
The virus attaches to the host cell, it takes over the functions of the host cell, and it eventually destroys it. If there was no host cell, the virus would die.
Yes. This is the reason that viruses infect cells. The virus injects its genetic material, either DNA or RNA, which then takes over the cell's activities and turns the cell into a virus factory, causing the cell to make new virus parts and assemble them. Eventually the cell ruptures and the new viruses are free to infect other cells.
A virus is not made from cells.
Once inside a cell, a virus's genetic material takes over of the cell's functions. It instructs the cell to produce the virus's proteins and genetic material. These proteins and genetic material then assemble into new viruses.
Virus have no cells
Bacteria are living cells -- cell membrane and all that cell stuff. A virus doesn't own it's own cell; it invades a cell and takes over, using the host cell to make more viruses.
No, a virus is not a cell and is not made of cells.
Any single celled organism carries out the functions of life, but, if considered living, a virus is much smaller than a cell. However, viruses are only DNA and can do little except control a cell with their DNA. They do not eat, or control their own movement, nor can they reproduce without a host.
Lysogenic virus.
