Compare and contrast the structure, life cycle, and host cell type of naked and enveloped viruses
What will be an ideal response?
Answer: A naked virus lacks an envelope and is called a nucleocapsid, because it contains only a nucleotide-based genome and capsid proteins. A virus containing a nucleocapsid enveloped within an additional lipid layer is called an enveloped virus. Most enveloped viruses are animal viruses, while naked viruses infect animal, plant, and prokaryotic cells. The penetration phase of the viral life cycle differs between enveloped and naked viruses. The entire enveloped viral particle typically enters an animal host cell during penetration, while many naked viruses only inject their genome during penetration. In addition, release of enveloped viral particles usually occurs through budding so that the host cell membrane drapes around the nucleocapsid. Naked viruses are more often released through cell lysis, especially in cell types with cell walls.
