Mutations and the Structure of DNA

 

DNA is more complex than we have discussed

            Nucleosome

            Exons vs introns

            "Junk DNA"

 

Mutations = heritable change in DNA

            Point mutations

                        Base substitutions

Insertions/deletions

                        Two examples of cause and effect

                                    Sickle-cell anemia

                                    Huntington's disease

            Chromosomal mutations

 

Applications of biotechnology

            Prokaryotic protein factory

            Modifying agricultural products

            Medical applications
