What a cell and a virus have in common is the RNA or DNA. The virus can be either a RNA virus or a DNA virus.
A virus is not similar to a cell, although it requires a host cell to reproduce. The only thing in common that a virus has to a cell is it has DNA.
Viruses cannot reproduce. They use a living cell to replicate themselves. When a virus infects a living cell, it injects its genetic material (DNA or RNA) into the cell. The virus' genetic material takes control of the cell and turns it into a virus factory. The cell does nothing but manufacture and assemble virus parts until eventually the cell ruptures and the new viruses erupt and go on to infect more cells.
takes over another cell and control it and it tells it to reproduce
No where. A virus is not a cell.
Ok, the common cold virus has little things around it that look like keys. The virus enters your respiratory tract, like the nose or mouth and goes to a cell, the little key-things try to open big proteins on a cell tha looks like a lock then, the molecules or organelles in a cell welcome the virus. When the virus enters the nucleus of the cell it goes to a "factory" and it uses our DNA to copy its own DNA, and it keeps reproducing until there are millions of them but luckily we have our immune system, white cells, and they "eat" the virus.
A virus.
Both a living cell and a virus contain nucleic acid. The virus has a capsid, whereas a living cell does not.
A virus does not have a metabolism. To reproduce, a virus takes control of a living cell, forcing the cell to make copies of the virus. All energy is provided by the cell.
It has no nucleus, though technically a virus is not a cell at all.
A virus will replicate within a host cell.
A virus and a cell have to have matching "docking" proteins for the virus to invade. Otherwise the virus is blocked.
A virus affects humans by invading a cell. The virus then forces the cell to produce viral material rather than cell material. This causes the cell to replicate the virus rather than itself.
