Substitution
Insertion
Inversion
Translocation
A change in a gene, group of genes or chromosome that results in a change in the proteins
Replication
Mutations
Translation
Transcription
One nucleotide base is changed so only one amino acid
is affected
Substitution Mutation
Point Mutation
Translocation
Inverse Mutation

Chromosomal Mutation
Translocation
Substitution Mutation

Translocation
Silent Mutation
Deletion Mutation
A nucleotide base is inserted or deleted shifting the entire DNA sequence. Entire protein will be changed.
