Changes to _______ will not affect the phenotype of an organism.

Question

Quizplus · Accepted Answer

A change in a codon that does not alter the encoded amino acid is known as a synonymous or silent mutation. These mutations do not result in a change in the amino acid sequence of the protein and, therefore, do not affect the phenotype of the organism. However, changes to other aspects of DNA, such as the nucleotide sequence of DNA that codes for protein, the positions of coding genes, the extent of noncoding DNA, or the location of noncoding DNA, can have significant effects on the phenotype of an organism.
