Researchers investigating the protein composition in mice have identified a new proteinand found evidence of sulfur-containing cysteine at regular intervals in its primarystructure.Which of the following best describes the most direct significance of this finding?ABсDThe secondary structure of the protein will include tightly would alpha-helices but nobeta sheets.The tertiary structure of the protein likely contains a relatively high number of bendsand angles.The protein will form a relatively highly stable tertiary structure.The dietary intake of mice must include the regular ingestion of cysteine.

Protein structure The structure of proteins are made by condensation of amino acids through the formation of peptide bonds. This amino acids sequence is the primary structure. The secondary structure involves the dihedral angles of the peptide bonds while the tertiary structure involves the folding of protein chains in space.Correct option Option c- protein will form stabilized tertiary structure Cysteine has a sulfhydryl group which is involved in the formation of disulfide bonds. The disulfide bonds stabilizes tertiary structure of the proteins, which is vital for extracellular proteins that are exposed to harsh conditions. Proteins having multiple disulfide bridges are more resistant to thermal denaturation. Incorrect options Cysteine directly affects tertiary structure of protein, not the secondary structure. Cysteine will not contribute towards the bends and angles. Dietary intake can not detected by this finding.
