What is the correct order of assembly in the cell?

The correct order of assembly in the cell starts with amino acids, which are the building blocks of proteins. During the process of translation, ribosomes string together individual amino acids in a specific sequence dictated by mRNA to form a polypeptide chain. This polypeptide then undergoes folding and modifications to form a functional protein.

Recognizing this sequence is crucial because amino acids are first linked together to create polypeptides, which in turn fold and may undergo further modifications to achieve their final form as proteins. This process demonstrates how the primary structure (the sequence of amino acids) ultimately dictates the tertiary structure (the functional protein).

Therefore, the correct sequence—starting with amino acids, moving to the formation of polypeptides, and culminating in the final protein—is accurately represented in the answer choice.
