  • DNA
    • The molecule has two strands coiled together in the shape of a double helix
      • Each strand is made up of lots of small units called nucleotides
        • Each nucleotide contains a small molecule called a base
    • A gene is a section of DNA  that contains the instructions for one particular protein
      • Cells make proteins by joining amino acids together in a particular order
        • The order of the bases in a gene that tells the cell in what order to put the amino acids together
          • Each set of three bases codes for one amino acid
    • Proteins are made in the cell cytoplasm by organelles called ribosomes
    • It is found in the cell nucleus and can't move out of it because it is really big
    • To get information from the DNA to the ribosome, a copy of the DNA is made using a molecule called messenger RNA
      • Messenger RNA is very similar to DNA but its much shorter and only a single strand
