DNA MUTATIONS

MUTATIONS CAUSED BY DNA

POINT MUTATIONS

For point mutations, a single nitrogenous base is changed at one point. An example would be THE DOG BIT THE CAT and after a nitrogenous base is changed (a letter) it changes to THE DOG BIT THE CAR. Point mutations cause things like sickle cell anemia.

Frameshift Mutation

Frameshift mutations are caused when a single base is added or taken away from DNA. This causes the entire strand to shift, making the codon reading off by one base. This causes issues such as Cystic Fibrosis and Lou Gehrig's Disease.
