If you use Windows on your machine, like me, you will have a small button at the the bottom of your screen called &lsquo;Start&rsquo;. Every machine in the world which has the Windows software installed has to have that button. However, we can have different screen colours, different text sizes, wallpapers etc.</p> <p>Similarly our bodies are essentially the same, but we have different colours, sizes, shapes and structures. Our body also has a software which is responsible for these differences between one human being and another. It is called the DNA.</p>
