  • DNA
    • Contains all the instructions to put an organism together and make it work
    • found in the nucleus of animal and plant cells
      • In really long molecules called chromosomes
    • genes
      • section of DNA which contains instructions to make a specific protein.
        • cells make proteins by stringing together amino acids in a particular order
          • only 20 amino acids are used, but they make up thousands of different proteins
            • genes tell cells which order to put the amino acids in
    • DNA Fingerprinting
      • cutting up a persons DNA into small sections and then separating them
      • Forensic Science
        • If the patterns match, that person was probably at the crime scene
        • DNA from hair, skin, blood or semen is taken and compared with the suspects DNA.
      • Paternity testing
        • To see  if a man is the father of a baby
          • Half the DNA will be the  mothers and half the DNA should match the fathers.
