As amino acids are put together, their determines the way in which they will fold into a three-dimensional structure. It is the of the folded structure that determines its function.

Explanation:

Gene is a section of DNA that is required to make a protein.The section of DNA undergoes transcription in order to synthesize a protein. As amino acids are put together, their order determines the way in which they will fold into a three-dimensional structure. It is the shape of the folded structure that determines its function.
