DNA Instruction Manual
The DNA double helix structure is a now a rather famous image. The instructions for the cell are written in a code using only four letters, normally written as A, C, G, and T
Most of us are familiar with the idea that computers work by reducing everything to a code of only two numbers '0' and '1'.
Also well known is the idea that Morse code can use dots and dashes to quickly transmit complex messages. This code is frequently seen on war movies; the most famous Morse message being “...---...” or “SOS” the international distress signal.
So, it should be no surprise that something as complex as a human being can be reduced to a code of four letters. However, the world is a rough place to live and our DNA code is constantly being damaged.
