Question

Quizplus · Accepted Answer

A premature stop codon created by a point mutation is called a nonsense mutation. Synonymous mutations are those that do not result in a change in the amino acid sequence, while nonsynonymous mutations result in the substitution of one amino acid for another. "Translation" refers to the process by which the mRNA sequence is translated into a protein sequence, and "transition" refers to a specific type of point mutation where a purine (A or G) is replaced by a different purine, or where a pyrimidine (C or T) is replaced by a different pyrimidine.
