In this article we will discuss about the details of structural genes. Structural Genes: They control amino acid sequence of a protein by producing mRNA. There are as many structural genes as there are proteins which are regulated. Either a single mRNA is transcribed from each structural gene or, all the structural genes of an operon form a single polycistronic [...]

In this article we will discuss about the genetics of viruses. History of Viruses: Viruses were first discovered in 1899 when M. W. Beijerinck noticed the existence of microorganisms invisible in the microscope, that could pass through filters that stopped bacteria. In 1917 Felix d'Herelle gave the name bacteriophage (meaning eater of bacteria) to one such microbe that was parasitic [...]
