the p53 gene was discovered in 1979, but it was not clear whether the gene functioned as an oncogene or a tumor-suppressor gene. Several years later, researchers showed that both p53 alleles are inactivated in some mouse cancers. This evidence suggests (1 point)Responsesthe p53 gene is an oncogene because inactivated alleles would produce mutated signal transduction proteins that would result in stimulating cell division.the p53 gene is an oncogene because inactivated alleles would produce mutated signal transduction proteins that would result in stimulating cell division.the p53 gene is an oncogene because the cell would overproduce transcription factors to compensate for the inactive alleles, resulting in increased cell division.the p53 gene is an oncogene because the cell would overproduce transcription factors to compensate for the inactive alleles, resulting in increased cell division.the p53 gene is a tumor-suppressor gene because inactivated alleles indicate a loss of protein function which allowed the cancer to develop.the p53 gene is a tumor-suppressor gene because inactivated alleles indicate a loss of protein function which allowed the cancer to develop.the p53 gene is a tumor-suppressor gene because the cell would produce too few transcription factors for gene activation, resulting in decreased cell division.

the p53 gene is a tumor-suppressor gene because inactivated alleles indicate a loss of protein function which allowed the cancer to develop.
