- determine which statements is either tumor supressor or proto oncogeneThe genes for retinoblastoma (pRB) and p53, act as ________ in regulating the cell cycle. oncogenes proto-oncogenes pseudo-oncogenes tumor enhancer genes tumor suppressor genesp53 is a gene / protein often associated with cancer. Why? What does p53 do? What kind of gene is it? Is it associated more with any one particular type of cancer or all cancers? Tell me more about p53, but please do not exceed one typed page.
- Cancer is a genetic disease. To provide evidence that you understand cancer genes are altered in both sporadic (somatic) and inherited cancers, match the beginning and end of the sentences below to give correct statements.Relatively few inherited forms of cancer involve the inheritance of mutant oncogenes. Instead, most inherited forms of cancer are defects in tumor-suppressor genes. Give two or more reasons why inherited forms of cancer seldom involve activated oncogenes."In the cellular regulatory pathways that control cell growth and proliferation, the products of oncogenes are stimulatory components and the products of tumor suppressor genes are inhibitory components" is true or false.
