Answer: Polypeptide chain
Protein (after modifications)
Step-by-step explanation:
Translation is the process of protein synthesis where the sequence of mRNA is translated into a polypeptide chain. Therefore, the only molecule produced by translation is a polypeptide chain, which is the primary structure of a protein.
However, after translation, the polypeptide chain undergoes various modifications to become a functional protein. These modifications include folding, cleavage of signal peptides, phosphorylation, glycosylation, and formation of disulfide bonds. Therefore, the following molecules can be produced by translation, subject to further modification:
Polypeptide chain
Protein (after modifications)
So, the correct answer is:
Polypeptide chain
Protein (after modifications)
