Virus core

Definition

The virus core is the innermost part of a virus, consisting of its genetic material and associated proteins. It is crucial for the virus's ability to infect host cells and replicate.

5 Must Know Facts For Your Next Test

1. The virus core contains either DNA or RNA as its genetic material.
2. Proteins within the virus core are essential for protecting the viral genome.
3. The composition of the virus core can determine the classification of the virus.
4. Virus cores are enclosed by a protein coat called a capsid.
5. Some viruses have an additional lipid envelope surrounding the capsid.
