Genome of Oncorna virus provides the information on carcinogenesis of an infected cell. This is evident from the fact that a different morphology of the focus is observed when a different strain (type) of a virus group would infect the same kind of host cells.
Physiological conditions of the cells, such as cell cycle, macromolecular syntheses, cell crowdiness, and media also exercise an influence upon fixation and development of the viral genome.
