The document discusses different types of mutations in DNA, including point mutations and frameshift mutations. A point mutation is when a single nucleotide is changed, like changing an A to a C. A frameshift mutation occurs when a nucleotide is inserted or deleted, shifting the reading frame and changing all subsequent codons. The document provides examples of normal DNA sequences and how point and frameshift mutations would alter the sequences and change the resulting protein code.

code (mutation)
important for survival?
Give an example.

happens when a letter is
altered?
