Which of the following is true about protein molecules?

a. the sequence of amino acids that make up a protein molecule do not affect its function.

b. protein molecules have many functions in the body, including the storage of genetic information.

c. protein molecules are made up of strands of dna joined together by amino acid sequences.

d. the shape and folded structure of a protein molecule are important in determining its function.

The correct answer is- D. The shape and folded structure of a protein molecule are important in determining its function.

Proteins are the most diverse group of biologically essential organic molecules that are considered to be significant for life. The basic monomeric unit of protein is amino acid whose sequence affects the function of the protein.

Biologically active form of proteins is their three dimensional structure ( native and active form) that is produced by the folding of protein molecule after it gets synthesized.

Therefore, shape and folded structure of a protein molecule are important in determining its function.
