  5. Mutation Pages 307-308 By PresenterMedia.com

  6. Mutations • Some are positive • Some are negative • Some have no effect • Amino acids have multiple codons • Pick a number 1-10… • Mutagen= Chemical or physical agent that causes a mutation • ?

  7. Mutagens • Chemical or physical agent • Chemical agents • Benzene, formaldehyde • Plant alkaloids-corn lily • Smoke • Pollutants • Physical agents • Xrays • Buster Brown Shoes • UV Light • Radiation

  8. Harmful effects of mutation 2. Sickle cell 1. Cancer

  9. Beneficial effects Beneficial to whom? • Resistance to pesticides • Bed bugs • Resistance to antibiotics • MRSA, VISA, VRSA • Plant and animal breeders • Polyploidy • Plants are larger and stronger Triploid watermelons are sterile!

  10. Mutations • 2 different types of mutations • Gene mutations • Changes at the base level • Chromosomal mutations • Changes in the number or structure of chromosomes

  11. Gene Mutations 1. Point mutation • Substitution • Changes in a single gene • CTC glutamic acid hydrophilic • A is substituted for T • CAC valine hydrophobic • Causes sickle cell disease • The fat man ate the hot bbq rib. • The fit man ate the hot bbq rib.

  12. Gene mutations Frame shift mutations 2. Insertion • The fat man ate the hot bbq rib. • The fat emanat eth ehotbbqri b. 3. Deletion • The fat man ate the hot bbq rib. • The ftmanatethehotbbqr ib.

  13. Chromosomal mutations • Changes in the number or structure of chromosomes 1. Deletion • ACDEF 2. Duplication • ABBCDEF 3. Inversion • AEDCBF 4. Translocation • ABCJKL

  14. Gene Therapy Good or Evil? • Gene Therapy • Cystic Fibrosis
