31. Maturation is submitted by the assembly of bacteriophage DNA and capsids into virions . 32. The virions can then infect numerous cellular targets and disseminate into the whole organism. 33. The virion is pleomorphic; the envelope can occur in spherical and filamentous forms. 34. French families of de Virion and de Spiner. 35. Binding between Z and the viral envelope glycoprotein complex is required for virion infectivity. 36. Each virion contains three copies of the genome. 37. The inclusions may or may not ( depending on the species ) contain virions . 38. This complete particle is known as the virion . 39. These virions can infect survivors of the acute infection caused by the original virus. 40. The structure of the erbovirus virion is icosahedral,
