"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.

WebMutations that do not result in a change in the amino acid sequence of the protein are referred to as silent mutations. These mutations manifest themselves when the codon that specifies the amino acid is unaffected by the change. As a consequence of this, the RNA that is created during the transcription process will be similar to the RNA that ... A silent mutation, which could easily include more than one nucleotide, could easily change an entire amino acid, or even series of amino acids. If a serine changed into a threonine, the effect might be minimal. The two amino acids are in the same category and are very similar shapes. See more The DNA is read in units of three nucleotides, called codons. Each codon specifies a certain amino acid, with a few reserved as stop and start signals.
