In a nutshell, the instructions on the DNA are converted into proteins in a two-step process: Special proteins read the information on the DNA string and convert it into a special messenger molecule called mRNA—basically the language that our DNA uses to communicate orders. The mRNA molecule is then transported from the nucleus of the cell to another organelle, the protein production machinery called the ribosome. Here the mRNA molecule is read and translated into amino acids, that are then put together in the order inscribed into it. And voila, the cell has made a protein from your DNA. So
