🦠 Viruses | Definition, Characteristics & Structure Explained

What is a virus? In this short biology video, we explain the definition, unique characteristics, and structure of viruses in a clear and simple way.

A virus is a microscopic infectious agent that can only replicate inside a living host cell. It’s acellular, contains DNA or RNA, and is covered by a protein coat (capsid). Some viruses have an envelope with surface spikes to attach to host cells.

🧬 Examples: Coronavirus, HIV, Influenza virus, Bacteriophage.

Learn how viruses work and why they are considered the bridge between living and non-living things.
