You have just sequenced a new protein found in mice and observe that sulfur-containing cysteine residues occur at regular intervals. what is the significance of this finding?

Cysteine residues are involved in disulfide bridges that helps to form tertiary structure in a protein

Explanation:

The tertiary structure of a protein will have a single polypeptide chain backbone with protein secondary structures. The interactions and bonds of the side chains within a protein determine its tertiary structure.

The cysteine forms the disulfide bridges and they link the fragments within a polypeptide chain. Sometimes those fragments are located very far from each other with respect to their primary structure. So, the tertiary structure is the three dimensional shape of a protein.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.
