<prompt> The normal cellular counterpas of oncogenes are impoant for the following functions, except ?Promotion of cell cycle progressionInhibition of apoptosisPromotion of DNA repairPromotion of nuclear transcription  <response>: o Normal cellular counterpa of oncogene is protooncogene.o The functions of protooncogene is to code forGrowth factorsGrowth factor receptorsProteins involved in signal transductionNeuclear regulatory proteins transcription factorsCyclinsCDKso All these lead to cell proliferation and progression of cell cycle.o When any of these protooncogenes becomes oncogene by mutation overexpression, there is uncontrolled proliferation of cell and development of cancer.This proliferation is autonomous, i.e. without physiological stimulus.
