Indicаte whether eаch оf the fоllоwing stаtements related to cancer is likely to be true or false. A cell line has a mutated Ras protein that is always active. A drug that can prevent the receptor tyrosine kinase from binding to the growth factor will not inhibit the division of this cell line. [1] The inhibition of negative immune regulation has been used to develop anti-immune-checkpoint antibodies. These antibodies release a killer cell attack on cancer cells. This has been used for effective treatment of metastatic melanoma. [2] Because cancer cells divide faster than normal cells, they are more dependent on other cells to provide growth factors. [3] S-CDK should be classified as a potential oncogene. [4] Tumor progression involves successive rounds of randomly inherited change followed by natural selection. [5] Many cancer cells activate telomerase to bypass the built-in limit to cell proliferation.[6] Because certain mutations in tumor suppressor genes contribute to cancer development, cancer researchers should be attempting to design drugs that will inhibit tumor suppressor genes like p53.
