1. Genetic Mutations Objectives:
8.4 Relating ways chance, mutagens, and genetic engineering increase diversity Examples: insertion, deletion, translocation, inversion, recombinant DNA

2. Insertions Can be three types:
Point mutation
Frame-shift mutation
Insertion
Point mutation: a change in a single base of the gene sequence.

3. Insertions
Frame shift mutation: one or more bases are inserted or deleted, shifting the other bases, sometimes into nonsense.

4. Insertions
Insertion: the addition of extra DNA (CAN result in frame-shift mutations)

5. Deletions A portion of DNA is deleted from a chromosome.
Can range from no effect to death.
This is the cause of 2/3 of case of Duchenne muscular dystrophy.

6. Translocation
A transfer of genetic information between 2 nonhomologous chromosomes.
