DNA Code

You know what DNA is, that immensely complicated and big molecule at the center of all the cells in your body - and all the cells in every living thing. Segments of DNA are genes that code for how the cell must build a perfect, working protein .

There are thousands of proteins. Each protein is a string of amino acids, and a short protein is 150 amino acids long in a specific order. If one of these proteins (string of amino acids) is incorrectly assembled, it is destroyed by a quality control mechanism because they must be perfect.

So what are the odds that a code could develop by accident - randomly - to instruct a living body to build the thousands of proteins necessary for life?  The odds are small, like trying to hack a bike lock.

More on the bike lock analogy tomorrow.
