A mutation in a DNA coding region of a protein can cause

Question

Quizplus · Accepted Answer

A mutation in a DNA coding region of a protein can cause changes in all levels of protein structure (primary, secondary, tertiary, and quaternary) depending on the location and severity of the mutation. For example, a mutation that alters a single amino acid in the primary structure can affect the folding of the protein and its eventual three-dimensional structure. This, in turn, can affect how the protein interacts with other molecules and its overall function.
