Detailed explanation-1: -What, then, are oncogene products? These are the proteins involved in cell cycle regulation that operate by stimulating cellular growth and division (Figure 3).
Detailed explanation-2: -Oncogenes may cause normal cells to become cancer cells and grow in the body. Mutations that lead to the conversion of proto-oncogenes to oncogenes usually occur during a person’s lifetime and are not inherited from a parent.
Detailed explanation-3: -Cellular proto-oncogenes code for a number of proteins involved in cell proliferation, including growth factors, growth factor receptors, signal transducers within the cell cytoplasm and nuclear-regulating proteins.
Detailed explanation-4: -Introduction to Proto-oncogenes Mutations in proto-oncogenes are typically dominant in nature, and the mutated version of a proto-oncogene is called an oncogene. Often, proto-oncogenes encode proteins that function to stimulate cell division, inhibit cell differentiation, and halt cell death.
