What Is A Virus ? | Best Learning Videos For Kids | Dr Binocs | Peekaboo Kidz

Viruses are extremely tiny, even smaller than bacteria, making them invisible to the naked eye.

Unlike bacteria, viruses lack a cytoplasm, nucleus, or other cell-like structures.

They have a basic structure consisting of DNA covered by an outer protein shell and some fats.

Viruses are not considered living organisms as they cannot reproduce on their own; they need a host to multiply.

Once a virus enters a host, it hijacks the host cell by entering through its membrane.

The virus then takes over the host cell's protein-building structures, forcing them to replicate the virus instead of their own components.

The infected cell produces an army of viruses until it explodes, releasing the viruses to infect nearby cells, thus spreading the infection.
