| The RT enzyme converts the single-stranded virion into doublestranded DNA for subsequent integration into the host cell genome. |
|
| First, with respect to virion structure, the virions of both evolved from an icosahedral symmetry to a reniform or bacilliform shape. |
|
| The virion reproduces itself as from its genetic material only by replicating its genome. |
|
| The virion of MuLV classifies it as a C-type virus, which assembles at the surface of infected cells, and acquires a plasma membrane envelope as it buds from a cell. |
|
| The virus itself is a spherical enveloped virion, between 80 and 160 nm diameter, and has single stranded RNA of about 30 kilobases, the largest genome of all ssRNA viruses. |
|
| Efective vaccination of cattle using the virion G protein of bovine ephemeral fever virus as an antigen. |
|
| The concatemers are processed into mature chromosomes with cohesive ends, and packaged into prohead shells, during virion assembly. |
|
| Glycoprotein allows the virion to attach to a receptor on the host cell surface and thereby fuse with the host cell membrane, leading to infection. |
|
| We examined the efficiency of plaquing and phage virion integrity, as determined by in vitro assembly, immunological detection and electron microscopy. |
