Don't trust me on this one, but i'll say d.
<span>The two factors that determine the shape of a protein </span><span><span>
1. </span> Primary structure. The sequence of amino acids. Amino acids are the building blocks of protein. It is a strong of linearity that can be thousands in length. Moreover, the formation of the amino acid and its system is influenced by its genes’ nucleotides arrangement. </span>
<span><span>2. </span>Hence the next factor is how is the structure of the amino acids bended and folded with itself that forms the certain protein molecule and forms the larger complex structure</span><span> </span>
