Answer the following question given this paragraph: 

A point mutation is a change in a single nucleotide 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 below . The effects of point mutations depend on how they change the genetic code. You can watch an animation about nonsense mutations at this link: http://www. biostudio. com/d_%20Nonsense%20Suppression%20I%20Nonsense%20Mutation. htm .
