Detailed explanation-1: -Oncogenes or mutated copies of the proto-oncogenes may lead to uncontrolled cell growth and the escape from cell death, which may result in cancer development.
Detailed explanation-2: -Most cancer-causing DNA changes occur in sections of DNA called genes. These changes are also called genetic changes. A DNA change can cause genes involved in normal cell growth to become oncogenes. Unlike normal genes, oncogenes cannot be turned off, so they cause uncontrolled cell growth.
Detailed explanation-3: -Introduction to Proto-oncogenes Proto-oncogenes are a group of genes that cause normal cells to become cancerous when they are mutated (Adamson, 1987; Weinstein & Joe, 2006). Mutations in proto-oncogenes are typically dominant in nature, and the mutated version of a proto-oncogene is called an oncogene.
Detailed explanation-4: -An oncogene is a gene that when mutated or expressed at abnormally high levels contribute to converting a normal cell into a cancer cell. Cancer cells are cells that are engaged in uncontrolled mitosis. Video Explanation.
