Question

You have seen that most students are able to memorize the levels of structure in a protein-primary, secondary, tertiary, and quaternary. The question now becomes how to aid the students in visualizing and understanding that the sequence of amino acids will impact ionic or hydrogen being that will induce curves (alpha -helix) or folds(beta-sheets) in the amino acid chain. These curves and folds will be able to interact amongst each other and give the polypeptide (which is part of a protein or maybe the entire protein being made) a three-dimensional shape that will enable the polypeptide to bind to another polypeptide and form a complete protein. Rank the following groups in the order that they contribute to the structure of a protein.

Explanation / Answer

The following is the order(starting from highest contributing) in which they contribute to structure of protein: amonoacid sequence, alpha helix or beta sheets, polypeptide A joined to polypeptide B which is joined to polypeptide C, helix sheet turn helix. The first one contributes to primary structure, second one to secondary structure, third one to tirtiary structure and the last one to supramolecular complexes.
