- The p53 protein was discovered through its association with SV40 T antigen and assumed initially to be an oncoprotein. a. What is the current consensus as the function of p53 and what evidence caused this change in view? b. How does the effect of mutation in the p53 gene differ from the effect of mutation in the RB gene what is the molecular basis for this difference ?How might a point mutation in DNA affect the phenotype. How the genome is expressed in the organism? (Please explain this at the molecular level).d)To cause cancer, proto-oncogenes require (1 or 2)allele(s) to be mutated and therefore are considered (dominant or recessive). The mutation results in a (loss or gain) of function. For each underlined pair, boldface one. e)To cause cancer, tumor suppressor genes require (1 or 2)allele(s) to be mutated and therefore are considered (dominant or recessive). The mutation results in a (loss or gain) of function. For each underlined pair, boldface one.
