11. The Astroviridae capsid is related to those of the Tymoviridae. 12. All of the non-enveloped families have icosahedral capsids . 13. It has two open reading frames encoding a replicase and capsid protein. 14. Many viral capsids are formed by hexameric and pentameric proteins. 15. Rep proteins participate in the integration of the genome into preformed capsids . 16. Assembled capsid protein alpha is cleaved into capsid protein beta and gamma. 17. Assembled capsid protein alpha is cleaved into capsid protein beta and gamma. 18. The capsid encloses the genetic material of the virus. 19. Through this portal, viral DNA or RNA is transported into the capsid . 20. The pgRNA is inserted into an assembled viral capsid containing the viral polymerase.
