They have genetic materials. They have DNA or RNA
viruses
when a virus enters a cell and is active, it cause the host cell to make new viruses, which destroy the host cell.
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.
Users should run a virus scan often to make sure their computer of free of viruses. New viruses are created on an almost daily basis. For more information on virus protection visit Answers.com.
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.
An "active virus" is when a virus enters a cell and is active, it causes the host cell to make new viruses. This process destroys the host cell. The steps are first, the virus attach's to a host cell. Second, the virus's hereditary material enters the host cell. Third, the virus's hereditary material causes the cell to make viral hereditary material and proteins. Fourth, new viruses from inside the host cell. Fifth, new viruses are released as the host cell bursts open and is destroyed. There are five steps on how a active virus functions inside a cell.
There are new viruses everyday, 10s of thousands of new viruses. Some virus will be detected and some will not, it is best to scan and clean your computer for viruses. I recommend doing this every week or so.
The virus takes over a cell's DNA and forces it, along with some of the viruses own DNA as a 'blueprint' to make more viruses. Hope this helped!
Yes, they need to do this so they can have a host to make duplicates of the virus. The cells act as a host providing the materials and work to create new viruses. See the related questions below about the Lytic cycle for more information on virus reproduction.
Viruses.
Viruses use their DNA or RNA to replicate themselves within a host cell. They hijack the cell's machinery to make copies of their genetic material and produce new virus particles, which can then infect other cells. This leads to the spread of the virus within the host and potentially to other individuals.
When a cell is full of a new virus, the virus hijacks the cell's machinery to replicate itself. This replication process can eventually lead to the death of the host cell and the release of new virus particles that can then infect other cells in the body.
