Genetic Mutations, Diseases & BioTechnology March 2017
Other mutations – good?
What is a mutation? A mistake in copying DNA May be a single gene (point mutations) OR whole chromosome (frameshift) Cancer
How Mutations Occur and some examples may include..
Types of mutations
A genetic disease caused by Frameshift: Tay Sachs
A genetic disease caused by deletion: Cystic Fibrosis
A genetic disease caused by duplication: Huntington’s Disease
A genetic disease caused by inversion: Hunter Syndrome
Nondisjunction
A genetic disease caused by translocation & nondisjunction: Down Syndrome a.k.a. Trisomy 21 ****
Biotechnology: Genetic Engineering
Selective Breeding Allowing organisms with desired characteristics to breed
Ex. Dog breeds
Transgenic Organisms Inserting genes from another species Ex. Glow-in-the-dark bunny

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