MULTIPLICATION The process of viral multiplication involves several discrete steps . First, the virus must recognize and attach to its host cell. Generally, viruses are limited as to the type of host cell in which they can multiply and so recognition is often very specific. Viruses adsorb to their host cell surface via specific antireceptor molecules, often glycoproteins. Adsorption is generally temperature and energy independent. Penetration into

Unformatted text preview: the host cell, however, is often energy dependent and may occur by three different mechanisms; 1) translocation of the plasma membrane, 2) pinocytosis into cytoplasmic vacuoles, or 3) fusion of the plasma membrane with the viral envelope. Non-enveloped viruses may enter via translocation or pinocytosis; enveloped viruses typical enter via fusion. Once inside the host cell, uncoating releases the viral genome to be replicated....
