Telomerase Activation

In tumor cells is expected to find changes that result: best answer will be given?

a. independence external growth factors and activation of telomerase increased apoptosis bc the absence of p53 and ras, which lacks activity GTPase d. E. A and C apply B and C apply

d. A and C applied: a normal cell growth is regulated by external signals. When that external regulation is no longer necessary to uncontrolled growth can occur. As cells without telomerase activity shall be subjected a number of repetitions. For C. P53 is a tumor suppressor protein that promotes apoptosis and protein Ras, which regulates cell growth. In the absence of GTPase activity, which means you can not stop and will therefore remain in the promotion of growth.
