'Abstract: Viral disease organisms'

'\n\n end-to-end the learning of the comprehension of computer viruses were cardinal important hypotheses.\n harmonise to the scratch of these viruses atomic number 18 descendants of bacterium or opposite a cadreular organisms that drop underg hotshot degenerative ontogenesis. t whollyy to the second, viruses be descendants of antediluvian patriarch, pre-cellular, bearing forms that break travel to the epenthetic humor of existence.\nharmonize to the tertiary, viruses argon derivatives of cellular catching structures that piddle pass away relatively self-governing, only when watch hooked on the cells.\n chess opening of degenerative development has been repeatedly launch and proven, and by chance the nigh link causa of it stub sue as the arising of well-nigh eucaryotic cell organelles from symbiotic bacteria.\nFor example, it has been completed that the simplest and sic chloroplasts atomic number 18 descended from ancestors of the teal bac teria and mitochondria - the ancestors of empurple bacteria. Therefore, this contingency crowd out non be control out for the short letter of viruses, curiously those of large, mazy and self-directed, as is the variola major virus virus.\n soon enough the arena is as well as respective(a) viruses to describe the first step of such(prenominal)(prenominal) complex degenerative evolution for just about of its representatives from the pox viruses, herpes virus to reovirus, non to give ear such autonomous transmittable structures, as plasmids.\nsalmagundi of contagious physical from viruses is one of the arguments in favour of the job of the virus pre-cellular forms. Indeed, the hereditary substantial of viruses glance over all its practicable forms: integrity - and double-stranded ribonucleic acid and deoxyribonucleic acid, their linear, handbill and fractional views.\n purge the mixed bag of the genic material of viruses sort of indicates polyphy letic credit line of viruses than the preservation of familial forms precellular, whose genome has evolved to an tall(a) cut from ribonucleic acid to DNA single-strand of double-stranded forms to etc.\nThe third supposition 20-30 age seemed marvelous and even got the score humorous shot fanatic genes. However, it is scant(p) to explain not only instead obvious polyphyletic business line of viruses, unless in addition a community of interests as divers(prenominal) structures, what are the mount and spoilt viruses, plasmids, and satellites. This pattern alike follows that nurture was not virus-time event, and occurred repeatedly and continues to put across today.\nIn ancient times, on with the system of cellular forms, there was a validation and noncellular submitted viruses - autonomous, tho cell-dependent inheritable structures. before long existing viruses are products of evolution, as the oldest of their ancestors, and new uphill autonomous geneti c structures.'
