      people can write books about what DNA is and how it codes for life so I’m afraid I will have to be brief! basically it is a double stranded chain made up of 4 different molecules A T C and G. In one person’s genome there are 3 billion of these molecules! For a good overview of topics I usually find youtube videos really informative 🙂
