Expert Solution

Step 1

The virus is a microscopic organism that infects other cells to survive. The virus can only replicate inside a host organism. The genetic material can be DNA or RNA which is enveloped by a protein coat. Once the virus gets attached to its host cell, it enters inside the cell and makes use of the cells machinery to replicate and cause damage to the host cell. The host for the viral infection can be any living organism, from bacteria to large animals and plants. But outside the host cell, they are not active. Virology is the branch of science that studies in detail about the virus.
