What do viruses need to reproduce?
A
they need genetic material
B
They need a host cell
C
They need bacteria
D
They need insulin
Explanation: 

Detailed explanation-1: -Viruses cannot replicate on their own, but rather depend on their host cell’s protein synthesis pathways to reproduce. This typically occurs by the virus inserting its genetic material in host cells, co-opting the proteins to create viral replicates, until the cell bursts from the high volume of new viral particles.

Detailed explanation-2: -A virus is a tiny, infectious particle that can reproduce only by infecting a host cell. Viruses “commandeer” the host cell and use its resources to make more viruses, basically reprogramming it to become a virus factory. Because they can’t reproduce by themselves (without a host), viruses are not considered living.

Detailed explanation-3: -Viruses survive outside our bodies because of how they are built. Specifically, they are pieces of genetic material (RNA or DNA) contained in a special coating of proteins called capsids. Viruses cannot replicate unless absorbed by cells in our body.

Detailed explanation-4: -They do not possess ribosomes and cannot independently form proteins from molecules of messenger RNA. Because of these limitations, viruses can replicate only within a living host cell.

Detailed explanation-5: -It is a molecule with genetic material, it can only replicate inside of the living cells of another organism. The virus’s genetic material takes control of the host cell and forces it to reproduce.
