Compare and Contrast Silent Mutations, Missense Mutations, and Nonsense Mutations

Question

Examlex · Accepted Answer

The Answer is All three point mutations describe one change in the nucleotide sequence. Silent mutations can have slightly modified protein structures or unmodified ones, as long as the nucleotide change does not result in any change of the phenotype. Missense mutations are more restricted in that a nucleotide change results in a particular amino acid (codon) change. Although a missense mutation will change the amino acid sequence, this again may or may not change the structure of the protein. A nonsense mutation is the most specific of all where the nucleotide sequence now contains an inserted non- native stop site. The premature halt of protein synthesis will result in a shortened protein structure.
