Growth factors work as signaling molecules. When they bind to receptors on target cells, they function to_____________

activate proto-oncogenes, stimulating cell division.

Which of the following statements best describes how alkylating agents work as chemotherapy?

Which of the following is true about mutations?

Mutations are changes in the nucleotide sequence of DNA.

Which of the following statements best describes the benefits of radiation therapy?

Radiation damages the DNA within cancer cells, either slowing down cell division or stopping it altogether. Incorrect Radiation therapy can be directed against specific cells and tissues within the body. Radiation therapy may shrink tumors, making them easier to remove surgically.
