In this episode we examine not only how DNA can replicate itself, but how genes build bodies and run them. 
DNA is simply a long chain of molecules called nucleotides.These chains are a code for the construction of proteins that are ling chains of amino acids. A protein is a long chain of amino acids strung together in a specific order. These chains fold up into large molecules that can have many properties. They build our bodies and control our biochemistry. Genes control the proteins by determining which proteins are created, how many, when they are created, and where in the body they are created.

Find out how lifeless molecules can make a living thing, like you.
