Naked virus structure
WitrynaA virus is an obligate intracellular parasite, meaning that it can only survive within a host cell and depends on it for replication and metabolic processes, e.g., protein synthesis. Viruses can be classified based on their genome (DNA or RNA) or other structural components, such as the capsid, the envelope, and the viral receptor proteins … WitrynaExtending outward and away from the capsid on some naked viruses and enveloped viruses are protein structures called spike s. At the tips of these spikes are …

Some viruses (adenovirus, Norwalk virus, or papillomavirus) are characterized as “nonenveloped” or “naked.” These viruses have a typical viral structure of a nucleic acid core surrounded by a protein coat (capsid).
