How Ras mutations are often found in cancers. Another protein that is often mutated in cancers is PTEN, an enzyme that hydrolyses PIP3, generating PIP2. Mutations that inactivate PTEN are found in 75% of gliomas. Suggest why inactivating mutations of PTEN are selected for in cell lineages leading to cancer.

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
