2 What exactly is a mutated gene?

3 Nope, that’s not it.

4 Mutations Change in genetic material Some have little effect on gene expression or protein function. Some have a large effect.

5 Harmful mutations may cause cancers or genetic disorders.

6 Good mutations might make altered proteins which would be beneficial in different or changing environments. (Lead to evolution/natural selection)

7 Types of Mutations Gene Mutation (Point Mutation) – changes in one or a few nucleotides. Chromosomal Mutation – changes in number or structure of entire chromosome Comic Book Mutation – completely unrealistic mutation that takes place in comic books and movies.

8 Examples of Point Mutations

9 Substitution Change of one base to another. Usually only changes one amino acid in final protein. Examples of Point Mutations

10 Insertion Addition of 1 or more bases in nucleotide sequence. Causes frameshift

11 Deletion Removal of 1 or more bases. Causes frameshift Types of Mutations

12 The, Dog, Car, Arm, Red…
