Answer
This statement is not correct. The primary structure does not represent the active form but refers to the sequence of amino acids.
Step 2
B. has a very specific three-dimensional shape.

Answer
This is misleading. The primary structure itself is linear; the three-dimensional shape arises from subsequent folding.
Step 3
C. influences the way that the polypeptide folds.

Answer
While the primary structure plays a role in the folding process, it does not directly govern it. Thus, this answer lacks complete accuracy.
Step 4
D. directly controls the way proteins are transported into a cell.

Answer
This statement is correct. The primary structure encompasses the sequence of amino acids that ultimately affect post-translational modifications, which can influence cellular transport mechanisms.
