• The virus are simple forms of life with just either of the genetic material DNA or RNA(Not both) with a protein coat. They are survive even outside a host but they can not reproduce.They replicate or reproduce themselves after entering a host cell and activating the cell's mechanism to produce copies of themselves. There fore it is wrong to assume virus are not existent outside a host.They are inactive when outside a host and become active once inside a host. that's all
    • After the first sentence read "they survive instead of they are survive". thank u
