Why do viruses need to invade a host cell?

Short Answer

Expert verified

Viruses need to invade a host cell because viruses don't have the capability to reproduce, so they replicate themselves inside the host cell.

Step by step solution

01

Given Information

We have to find out the reasons of the need for a host cell for viruses.

02

Explanation

Viruses don't have the capacity to reproduce themselves because they are just single or double stranded DNA protected inside their coat called a capsid. So, in order to reproduce themselves, they need a host so that they can infect the host cell, and then the host cell will work for them by replicating viruses and creating thousands of viruses.
