In this article we will discuss about the replication of adenoviruses. Adenovirus replicates inside the nucleus (Fig. 17.9). By the DNA replication process, the adenovirus multiplication cycle is separated into two phases i.e., an early phase and a late phase. In both phases a primary transcript is formed which is spliced to produce monocistronic mRNA which is compatible with the [...]
Here is a list of viruses that are found in animals: 1. Papovaviruses 2. Simian Virus-40 3. Adenoviruses 4. Herpesviruses 5. Pox Viruses 6. Picornavirus 7. Togaviruses 8. Rabies Viruses 9. Influenza Viruses 10. Reoviruses. 1. Papovaviruses: Papovaviruses are one of the four important dsDNA viruses (e.g. papovaviruses, adenoviruses, herpes viruses and pox viruses) which produce tumour in many animals. [...]
In this article we will discuss about the structure of influenza viruses (explained with diagram). Particles of influenza virus are highly pleomorphic, mostly spherical having 80-120 nm diameter. But it also occurs in other form like long filamentous particles (2,000 nm long, and 80-120 nm diameter). They have helical symmetry also. The outer surface of the viral particle consists of [...]
