Answer:
The correct answer is option - 3) arrangement of amino acids in the protein.
Explanation:
The shape of the protein is determined by the arrangement of the sequences of amino acids in a protein which is known as the primary structure of a protein. The sequence or arrangement of the protein is based on the sequence of nucleotides in DNA.
The arrangement of the sequences of the amino acids forms the peptide bonds and hydrogen bonds that determine the shape of the protein. The shape of the protein determines the function of the particular protein in an organism.
Thus, the correct answer is option 3) arrangement of the amino acid in the protein.
