v In five kingdom classification virus does not exists because, it is not truse cell or acellular moiety. v It linked between living and non- living. v Virus are non- cellular organism that are characterized by having a inert crystalline structure outside the living cell. v Size- 20 to 400nm v Within the host cell they replicate themselves and form multiple copy. v They were smaller than bacteria ,and this experiment performed by M.W.Beijerinek. v Virus are obligate parasite( host is necessary for their survival). Important points
BEST FOR You O R G A N I C S C O M P A N Y Ultrastructureof virus • Structure- Made up of protein and genetic material ØThe protein coat called capsid. ØCapsid is made up of small subunit known as Capsomere,Which is arrange in helical or polyhedral geometric form. ØIn virus, genetic material is either RNA or DNA ØIt might be single stranded or double stranded. 4
LIFE CYCLE Firstly, viruses are usually specific in the type of cells that they infect(Every body has a pattern of protein on its surface called receptor). The genetic material of the virus infecting the cell is DNA. However, unlike the complex DNA found in the nucleus of a cell. The DNA of a virus is relatively simple, and just contains the information needed to manufacture new virus parts Once inside the cell, the instruction in the DNA are transcribed to RNA The protein building machinery of the host cell then translates these instruction into the components of a new virus.When ready, they emerge from the host cell often killing it in the process. Lifecycle continues…….

BEST FOR You O R G A N I C S C O M P A N Y 7 TYPES OFVIRUS Human Immunodeficiency virus Hepatitis-B Viral hepatitis is an infection that causes liver inflammation and damage. It is a unique type of retrovirus which invadesT-helper cells in host body. Adenovirus This virus can causes illness in people of all age any time of year. Bacteriophage This particular virus that only infect bacterial cell and reproduce inside the cell. Papilomavirus Human papillomavirus is the most common sexually transmitted disease.
