The gene that encodes Retinoblastoma (Rb) protein is a conserved gene in plants and animals. This gene has the primary control over whether the cell continues to divide or to differentiate. When it is activated, Rb represses the gene required to replicate the DNA. Which of the following happens when Rb is inactivated in the stem cells of vertebrates?
