here is some help: these to photos should give you the answer to this chart hope it helps.

Synthesis of a protein destined to function in the nucleus occurs AT THE RIBOSOMES.
Proteins are synthesized in the ribosomes. Newly synthesized proteins that are meant for the nucleus usually possess a localization sequences which direct it to a protein on the nuclear membrane through which it will enter into the nucleus.<span />
Answer:
Due to number of amino acids.
Explanation:
The main differences might be expected in the amino acid composition of X versus Y because the X polypeptide is made up of one smaller unit of amino acid while on the other hand, Y polypeptide is made up of four smaller units of amino acids. The name of X is monomer which means composed of one amino acids while Y exists as a tetramer which means it has four amino acids. So we can conclude that the main difference between X and Y is the presence of number of amino acids.
