THEBIGFATREDCATSAT is the normal message, what type of mutation is this: ZHEBIGFATREDCATSAT

• Insertion

• Deletion

• Substitution

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

A substitution mutation that has no effect

on amino acids sequence

• Insertion Mutation

• Translocation

• Silent Mutation

• Deletion Mutation
