In this article we will discuss about the strategies and types of antiviral drugs. Strategies of Antiviral Drugs: Antibiotics which have revolutionized the control of diseases caused by bacteria and some other pathogenic agents are totally ineffective against viruses, because the viruses do not have a cell and they are heavily dependent on the host cell for multiplication. Therefore, the [...]
The following points highlight the two main steps involved in the process of reproduction in plant viruses. The steps are: 1. Entry of Virions Into Host 2. Replication. Step # 1.

A virus is a pathogenic agent, a infections particle, consisting of a core of nucleic acid (DNA or RNA) enclosed in a protein shell. Viruses are, in general, much smaller than bacteria and have a much smaller genome. But their genetic material is of many varieties, unknown in cellular organisms. Some of these are discussed here. Bacteriophage φX174 which attacks [...]
