WebSep 4, 2024 · A point mutation is a change in a single nucle otide in DNA. This type of mutation is usually less serious than a chromosomal alteration. An example of a point mutation is a mutation that changes the codon UUU to the codon UCU. Point mutations can be silent, missense, or nonsense mutations, as shown in Table 6.6.1. A nonsense mutation occurs when the sequence of nucleotides in DNA is changed in a way that stops the normal sequence of amino acids in the final protein.
