Does a virus need a host cell?

Answer 1

Yes, they implant their DNA into a cell. The DNA tells the cell to replicate the virus inside itself. When the cell is full of the virus, it explodes, releasing viruses all around the targeted area.

Answer 2

Yes, viruses need a living host to replicate. A virion needs to be inside a living cell in order to "hijack" that cell so that more virus particles can be made by the cell.

Since a virus is not a living thing, it doesn't reproduce in the same way that living cells reproduce. For more detail about the Lytic cycle in the viral replication process, there is additional information in the answers to the questions in the related questions section.

Answer 3

Yes, virus replication is solely dependent on host cell machinery. Virus can not grow or replicate outside its host. Virus insert its genome (can be DNA or RNA) or capsid packaging its genome into the cell for infection. After successfully, integrated into the host genomic DNA, the viral DNA can be triggered by host cell machinery to make viral RNA/DNA/proteins. They package together to form progeny virus particles (need not to burst our host).

Answer 4

Without a host cell a virus can not replicate, so, yes, a virus needs a host cell.

Answer 5

Viruses are obligate intracellular microorganism so they require a host to reproduce

Answer 6

i think its because viruses don't have a nucleus so they have to convert a healthy cell into a sick cell to produce more copies of themselves.

Answer 7

It depends on what type of blood you have

Answer 8

yes they do

Answer 9

Yes
