Explain the relationship between the terms virus particle, virion, and virus genome

What will be an ideal response?


Answer: A virus particle is a broad term used to describe a virus at any stage of infection, whereas a virion is one single virus particle that is at an infectious state. They are metabolically inert in both cases and minimally contain a DNA- or RNA-based genome and a protein capsid layer. A viral genome is packaged within both a virion, containing a single or double stranded nucleotide sequence that serves as a template to produce viral transcripts and ultimately their proteins.
