Radiation and chemotherapy can also kill normal, healthy cells.
Radiation treatment utilizes high-energy particles or surges, such as electron beams, or protons, x-rays, gamma rays, to destroy or damage cancer cells. It operates by preventing the cancer cells from multiplying and dividing to make more cells. Because cancer cells normally grow and distribute faster than normal cells, chemotherapy has a larger effect on cancer cells. However, the drugs used for chemotherapy are persuasive, and they can still generate injury to healthy cells.
The cell organellles are visible in the electron microscope, but it is not possible to study the living cells in electron microscope. For study of genetic materials i.e., DNAs and RNAs is poosible through the help of electron microscope. (ANSWER)
