In this article we will discuss about the assembly, evolvement and release of herpesviruses. Assembly of Herpesviruses: There are more than 30 HSV-1 gene products that act as the structural components of the virion. These are expressed with late kinetics. Capsid assembly i.e. enveloping is a complex process. The general outline of the process was established by careful electron microscopic [...]
In this article we will discuss about the structure and replication of pox viruses. Structure of Pox Viruses: Oval or brick-shaped 200-400 nm long particles can be visualized by the best light microscopes. The external surface is ridged in parallel rows, sometimes arranged helically (Fig. 17.17). Viral particles (virions) are generally enveloped (external enveloped virion-EEV). The intracellular mature virion (IMV) [...]
In this article we will discuss about:- 1. Structure of HIV 2. Genome Organization of HIV-1 3. Steps of Entry 4. Replication 5. Assembly. Structure of HIV: HIV is different in structure from other retroviruses. HIV is of 100-120 nm diameters containing an protein envelope to which spicules of glycoprotein are attached. The envelope encloses an icosahedral capsid core that [...]
