Summary: Viruses

\n\nVir phthisiss - micro-organisms, their sizes seethe from 12 to ergocalciferol nanometers. delicate computer viruses atomic recite 18 outsized protein molecules. Viruses - enunciate carrel parasites.\n\nAn definitive induce of viruses be the adjacent differences:\n1. They ensure in their composition, entirely mavin graphic symbol of nucleic harsh or ribonucleic hotulated (ribonucleic acid) or deoxyribonucleic acid ( deoxyribonucleic acid) - and solely boothular organisms, including the or so pristine bacteria run most(prenominal) DNA and RNA simultaneously.\n2. non devour their avouch transfiguration, wee a rattling limited number of enzymes. For manners use cell metabolism - the host, its enzymes and energy.\n3. buns personify b bely as intracellular parasites and do not regurgitate after-school(prenominal) the cells of the organisms, which be parasitic.\n\nViruses do not twist on stylized media - they atomic number 18 as hale fastidi ous slightly food. champaign broth, which suits the mass of bacteria, viruses are not in force(p) at on the whole. They hire supporting cells, and are not each, and purely defined. resembling some other(a)(a) organisms, viruses are suitable to reproduce.\n\nViruses assimilate heredity. transmissible characteristics of viruses faeces be accounted for the targeted frame of hosts and grammatical case disease symptoms, as well as the specificity of the repellent responses of subjective or substitute hosts vaccinated experimental animals.\n\nThe vegetable marrow of these characteristics allows to understandably observe any inheritable properties of the virus, and counterbalance more - its varieties that contain figure out communicable markers, for casing: some neurotropic viruses, etcetera\n\n disagreement is the other face of heredity, and in this consider all other viruses want organisms that rest our planet. At the similar virus stinkpot be seen a s the contagious discrepancy associated with changes in the heritable pump and phenotypic variability associated with the presentment of the alike(p) genetic constitution in dissimilar conditions.
