Apoptosis Programmed Cell Death
We've touched on apoptosis before, especially when we learned about cancer in the biochemistry series. But let's a closer look. We know that apoptosis is programmed cell death, a failsafe mechanism whereby faulty cells that pose a threat...

The Cell Cycle and its Regulation
Your cells have to divide when you're growing, to heal wounds, and to replace dead cells. But how do cells know when to divide and when not to divide? We can't have cells just growing willy-nilly! That's what cancer is, and that's bad....

Protein Synthesis
Proteins are made of a long chain of amino acids, which has been coded for by DNA. The order of the bases of DNA determines which protein is made, by coding for a specific order of amino acids. This is protein synthesis, and in this...
