Viruses range from 20 to 300 nanometers in size, requiring electron microscopes for study.

Viruses consist of a core made of DNA or RNA encased in a protein coat called a capsid.

The protein coat surrounding the virus's genetic material (DNA or RNA).

Some viruses have an additional layer called an envelope that surrounds the capsid.

Viruses can only be visualized using an electron microscope due to their small size.
