      Great question!
      DNA, (the long name deoxyribonucleic acid) is in your cells in the nucleus, but mitochondria have their own DNA. The information in DNA is stored as code, which is 4 chemical bases adenine (A), guanine (G), cytosine (C), and thymine (T). which along with sugar and phosphate molcule make a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix which makes it look like a ladder. So DNA in the form of nucelotides (or the code) contains the instructions needed for an organism to develop, survive and reproduce.
      Hope this helps 🙂
