In a frame shift mutation, one or more bases are inserted or deleted, the equivalent of adding or removing letters in a sentence. This type of mutation can make the DNA meaningless and often results in a shortened protein. The fat cat ate the wee rat. The fat ca a tet hew eer at . Deletion Mutations that result in missing DNA are called deletions.
Deletions can also cause frameshift mutations.
In this example, the deletion eliminated the word cat. The fat cat ate the wee rat. The fat ate the wee rat. Insertion Mutations that result in the addition of extra DNA are called insertions. Insertions can also cause frameshift mutations, and general result in a nonfunctional protein.
