Nucleokapsidia

Nucleokapsidia are a type of viral particle that consists of a nucleic acid core surrounded by a protein capsid. The term is derived from the Greek words "nucleus" and "capsis," meaning "cover." These particles are found in both DNA and RNA viruses, and they are responsible for the transmission and replication of viral genetic material within host cells. The capsid provides structural support and protection for the viral genome, while also facilitating the entry of the virus into host cells. Nucleokapsidia can be further classified based on their capsid structure and symmetry, such as helical, icosahedral, or complex structures. They are a fundamental component of viral biology and play a crucial role in viral pathogenesis and immune evasion.
