Virus
This system based classification on phylum, class, order, family, genus, and species.
the four chemical bases that make up dna are adenine thymine guanine and cystosine Yes, that is correct. what is the full form of the abbreviation mentioned above? Deoxyribonucleic acid. what is it? It is a molecule composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. can you explain a bit more about the microorganism that you just mentioned? A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. from where does it get its name? Latin. by whom was it discovered? Bartholomeus Anglicus. what living features does it show? They possess genes, evolve by natural selection, and reproduce by creating multiple copies of themselves through self-assembly.

Virus [SEP] Classification
Classification seeks to describe the diversity of viruses by naming and grouping them on the basis of similarities. In 1962, André Lwoff, Robert Horne, and Paul Tournier were the first to develop a means of virus classification, based on the Linnaean hierarchical system. This system based classification on phylum, class, order, family, genus, and species. Viruses were grouped according to their shared properties (not those of their hosts) and the type of nucleic acid forming their genomes. In 1966, the International Committee on Taxonomy of Viruses (ICTV) was formed. The system proposed by Lwoff, Horne and Tournier was initially not accepted by the ICTV because the small genome size of viruses and their high rate of mutation made it difficult to determine their ancestry beyond order.
