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
