            "Junk DNA"


Mutations = heritable change in DNA

            Point mutations

                        Base substitutions

                                    Sickle-cell anemia

                                    Huntington's disease

            Chromosomal mutations


Applications of biotechnology

            Prokaryotic protein factory

            Modifying agricultural products
