O of the presence of normal cell tumor suppressor genes and gene products in the hybrid cell. O exposure to polyethylene glycol inhibits expression of oncogenes. O the normal cell DNA repair machinery reverses all cancer cell gene mutations. QUESTION 2 Each of the following is a mechanism by which proto-oncogenes are converted to oncogenes except Opoint mutation. O gene amplification. O translocation. O histone methylation. O deletion.
