Tumor is the uncontrolled growth of cells.In order to suppress tumor the cell cycle has to be inhibited, thus tumor suppressor genes encode proteins that inhibit cell cycle.
c. a single allele of an oncogene can result in uncontrolled cell division TRUE
A single allele of an oncogene can result in uncontrolled cell division as the mutation of one allele of a proto oncogene can convert it to oncogene as it can overexpress the gene product needed to drive the cell cycle forward.
