Ppt Virus Structure And Classification Powerpoint Presentation Free The document discusses viruses, defining them as infectious agents that can only multiply within host cells and consist of nucleic acids and protein coats. it covers virus structure, classification, life cycles, methods of transmission between hosts, discovery, theories of origin, and techniques for studying and cultivating viruses. the. This document provides information about virus structure and classification. it begins with the history of virology and defines viruses. it describes the differences between bacteria and viruses, and between dna and rna viruses. it outlines the characteristics, structure, replication process, and reaction to physical and chemical agents of viruses.
Ppt Virus Structure Classification Powerpoint Presentation Fr Viruses consist of genetic material surrounded by a protein coat. they can have dna or rna as their genetic material and come in various shapes. the document discusses the structure and classification of viruses. it describes their components, sizes, morphologies like helical and icosahedral shapes. it provides examples of plant, animal, and. Presentation transcript. virus structure and classification claude muvunyi m.d., ph.d. terminology in 1962, caspar et al. defined the following terms: • virion: the complete infectious virus particle. • capsid: the protein coat that surrounds nucleic acid. • nucleocapsid: the nucleic acid plus the capsid. • the nucleocapsid may be. A complete virus particle is called a virion. viruses are small obligate intracellular parasites, which by definition contain either a rna or dna genome surrounded by a protective, virus coded protein coat. viruses may be viewed as mobile genetic elements, most probably of cellular origin and characterized by a long co evolution of virus and host. for propagation viruses depend on specialized. How viruses multiply. (active viruses) virus attaches to the host cell virus injects genetic material viral dna or rna control production of viral protein and dna or rna protein and genetic material are assembled host cell bursts and virus is released. active viruses. active virus.

General structure and classification of viruses. general structure and classification of viruses. dr. mohammed arif associate professor consultant virologist head of the virology unit. the concept of virus. edward jenner in 1798 introduced the term virus to microbiology. virus in latin means poison. 728 views • 48 slides. Symmetry of viruses 2 helical symmetry : the virus particle is elongated or pleomorphic (not spherical), and the nucleic acid is spiral. caposomeres are arranged round the nucleic acid. 3 complex symmetry: the virus particle does not confirm either cubic or helical symmetry. cubic symmetry ( adeno & herpes viruses ).
