Question

once assembly of a new protein is complete, the polypeptide folds into a three - dimensional shape that is characteristic of that particular protein. match each of the following levels of protein structure with its description. primary structure (click to select) secondary structure (click to select) tertiary structure linear chain of amino acids linked by peptide bonds coiling of polypeptide chain quaternary structure twisted structure of a polypeptide chain that includes interactions between various amino acid groups on the chain comprised of two or more polypeptide chains

Explanation:

The primary structure of a protein is the linear sequence of amino - acids linked by peptide bonds. The secondary structure involves the coiling of the polypeptide chain (e.g., alpha - helices and beta - sheets). The tertiary structure is the twisted three - dimensional structure of a single polypeptide chain with interactions between various amino - acid groups. The quaternary structure is composed of two or more polypeptide chains.

Answer:

Primary structure: Linear chain of amino acids linked by peptide bonds
Secondary structure: Coiling of polypeptide chain
Tertiary structure: Twisted structure of a polypeptide chain that includes interactions between various amino acid groups on the chain
Quaternary structure: Comprised of two or more polypeptide chains
