So you want to be an intelligence analyst. Students occasionally write to me and ask for advice on getting a job in the Intelligence Community. (I became an intelligence analyst at DIA after undergrad. I was there for about three years, and after that, I did a few years of consulting for various intel agencies.) The below is a gist of that advice. It is heavily biased by my own experience, and none of the below is meant to be universal.
Apoptosis, or programmed cell death, is a naturally occurring process in the body. It involves a controlled sequence of steps in which cells signal self termination. Apoptosis works to keep the body's natural cell division process of mitosis in check.
Chemotherapy drugs that kill cancer cells when they are at rest are called cell-cycle non-specific. The scheduling of chemotherapy is set based on the type of cells, rate at which they divide, and the time at which a given drug is likely to be effective. This is why chemotherapy is typically given in cycles.he process of cell division, whether normal or cancerous cells, is through the cell cycle. The cell cycle goes from the resting phase, through active growing phases, and then to mitosis (division). The ability of chemotherapy to kill cancer cells depends on its ability to halt cell division.
