1 Genetic Mutations, Diseases & BioTechnology
March 2017

2

3 Other mutations – good?

4 What is a mutation? A mistake in copying DNA
May be a single gene (point mutations) OR whole chromosome (frameshift) Cancer

5 How Mutations Occur and some examples may include..

6 Types of mutations

7 A genetic disease caused by Frameshift:
Tay Sachs

8

9 A genetic disease caused by deletion:
Cystic Fibrosis

10

11 A genetic disease caused by duplication:
Huntington’s Disease

12

13 A genetic disease caused by inversion:
Hunter Syndrome

14

15 Nondisjunction

16 A genetic disease caused by translocation & nondisjunction:
Down Syndrome a.k.a. Trisomy 21 ****

17 Biotechnology: Genetic Engineering

18 Selective Breeding Allowing organisms with desired characteristics to breed

19 Ex. Dog breeds

20 Transgenic Organisms Inserting genes from another species
Ex. Glow-in-the-dark bunny

21 Video about genetic engineering and transgenic organisms

22 Cloning Produced from a single cell Genetically identical
Ex. Dolly the sheep

23

24 You tube video on cloning
Brainpop video & quiz

25 Stem Cells Definition Technology Examples Success story Brainpop

26 Genetic Screening Right? Wrong?

27 DNA Fingerprinting
