Although the virus or bacteria particles are destroyed and cannot replicate, the virus capsid proteins or bacterial wall are intact enough to be recognized and remembered by the immune system and evoke a response.
Another classification uses the geometrical shape of their capsid (often a helix or an icosahedron ) or the virus's structure (e.g. presence or absence of a lipid envelope ).
For example, the gag gene is translated into molecules of the capsid protein, the pol gene is translated into molecules of reverse transcriptase, and the env gene is translated into molecules of the envelope protein.
If this capsid protein is included in the DNA, the resulting vaccine can combine the potency of a live vaccine without reversion risks.
Linear layout of lambda phage genome with major operons, promoter regions and capsid coding genes.
Several dsDNA bacteriophages and the herpesviruses encode a powerful ATP driven DNA translocating machine that encapsidates a viral genome into a preformed capsid shell or prohead.
