In an adult, 50-70 billion cells die every day. This is normal. It could be due to damage, stress, or simply old age.
Right now, in your body, millions of cells are dividing and creating new cells to make up for this loss.
Cell division, or mitosis as it is also known, requires a small army of molecular machines. The double-helix DNA molecule is a great place to begin.
