The partial DNA sequence that will oncogene be expressed in the cell is 5' CCC ATC CAT.
Genes that code for positive cell cycle regulators are called proto-oncogenes. Proto-oncogenes are normal genes that, when mutated, become oncogenes—genes that cause cells to become cancerous.
Oncogenes are a mutated form of proto-oncogenes that under normal conditions play many roles in the process of cell division or proliferation. Oncogenes in cancer cells play a role in inducing cell proliferation so that cell division becomes uncontrolled. The underlying genetic mechanisms associated with oncogene activation include the following: Point mutations, deletions, or insertions that lead to hyperactive gene products.
