The concatemers are processed into mature chromosomes with cohesive ends, and packaged into prohead shells, during virion assembly. |
First, with respect to virion structure, the virions of both evolved from an icosahedral symmetry to a reniform or bacilliform shape. |
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 virion reproduces itself as from its genetic material only by replicating its genome. |
The RT enzyme converts the single-stranded virion into doublestranded DNA for subsequent integration into the host cell genome. |
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. |
