The HSV genome is large (152 kbp) and structurally complex, consisting of two unique regions (UL and US) flanked by inverted repeat sequences arranged as ab-UL-b′a′c′-US-ca (reviewed in Ward and Weller 2011, and references therein).The HSV genome contains three origins of replication: OriS is present twice in the viral … Name and describe the five steps of the replication cycle • 2.

The one-step multiplication curve for a bacteriophage population follows three steps: 1) inoculation, during which the virions attach to host cells; 2) eclipse, during which entry of the viral genome occurs; and 3) burst, when sufficient numbers of new virions are produced and emerge from the host cell. Although the replicative life cycle of viruses differs greatly between species and category of virus, there are six basic stages that are essential for viral replication. So far the receptors for the poxvirus are not known.

PowerShow.com is a leading presentation/slideshow sharing website. Surrounded by protein coat a. Capsid b. It's FREE! After releasing from the host cell, it infects new cells and can cause infections either for a short term or long term. Our mission is to provide a free, world-class education to anyone, anywhere. … Penetration - virus injects its genome into host cell. As viruses are obligate intracellular pathogens they cannot replicate without the machinery and metabolism of a host cell. Attachment requires specific interactions between components of the virus particle (eg, capsid proteins or envelope glycoproteins) and components of the host cell (eg, a glycoprotein or carbohydrate moiety). During the process of viral replication, a virus induces a living host cell to synthesize the essential components for the synthesis of new viral particles. Penetration (Entry) 3. Reovirus replication occurs in the cytoplasm. - Viruses What is a virus? Unlike animal viruses that attach, penetrate, and then uncoat, phages' penetration IS their uncoating.They attach and uncoat as they penetrate. Internationally, US is at the highest risk of being attacked by computer viruses, followed by Russia.
