Give a brief account of viruses with respect to their structure and nature of genetic material. Also name four common viral diseases.
Viruses are sub-microscopic infectious retailers which can infect all dwelling organisms. A virus includes genetic cloth surrounded through a protein coat. The genetic cloth can be gift withinside the shape of DNA or RNA. Most of the viruses, infecting plants, have unmarried stranded RNA as genetic cloth. On the opposite hand, the viruses infecting animals have unmarried or double stranded RNA or double stranded DNA. Bacteriophages or viruses infecting micro organism frequently have double stranded DNA. Their protein coat referred to as capsid is made from capsomere subunits. These capsomeres are organized in helical or polyhedral geometric forms. A.I.D.S, small pox, mumps, and influenza are a few not unusualplace examples of viral diseases.
