What is a Mutation?
A mutation is a permanent change in the DNA sequence of a gene. Mutations in a gene's DNA sequence can alter the amino acid sequence of the protein.
Some causes of mutations include: Radiation, carcinogens, and ultraviolet light.
What is a Deletion Mutation?
A mutation in which one or more bases are omitted from the strand.
Example:Regular sentence: Pet the bad cat
With a deletion mutation:1. Ptt heb adc at (e is deleted)2. Pet the cat (if three are deleted)
What is an Addition Mutation?
A mutation in which one or more bases are added.
Example:Regular sentence: Pet the bad cat
With an addition mutation:1. Pae tth eba dca t
What is a Frameshift Mutation?
When one or two bases are left out or added, and all of the codons after the mutation are now different. If 3 are bases are deleted or added, NO frame shift will occur.
Example:Regular sentence: Pet the bad cat
With a frameshift mutation:1. Ptt heb adc at2. Pet tth eba dca t
What is a Substitution Mutation?
A mutation in which one base is put in the strand in place of another
Example:Regular sentence: Pet the bad cat
With a substitution mutation:Put the bad cat
Usually NOT a frame shift mutation because there are still three codons in the base. Only one is messed up.
