Biology Notes on Retroviridae | Microbiology

The below mentioned article provides notes on retroviridae. The family Retroviridae falls under the Group VI (ssRNA-reverse transcribing viruses). The virions are enveloped, helical or isometric having two linear (+) sense ssRNA, reverse transcriptase and integrase. Examples are MLV [Murine leukemia virus and related virus e.g. Spumavirus (human foamy virus)], Lentivirus (human immunodeficiency virus or HIV), Visna virus, Deltaretrovints, Alpharetrovims. [...]

Structure of Picornavirus | Microbiology

In this article we will discuss about the structure of picornavirus. Each capsid is composed of 60 copies of four structural proteins of which each proto-meter consists of four polypeptides known as VP1, VP2, VP3 and PV4. VP1-VP3 are exposed on the virion surface, while VP4 lies buried in close association with the RNA core (Fig. 17.21). All the VP [...]

5 Main Stages of Animal Viruses | Microbiology

Animal viruses differ from stages in mechanism of entering the host cell. This is due to differences in host cell i.e. one is prokaryotic and the other eukaryotic in nature. It is accomplished into the following stages: 1. Attachment: Animal viruses like bacteriophages posses the attachment sites with the help of which it attaches to the receptor sites present on [...]
