The statement "multiple polypeptide chains are held together by a variety of bonds" refers to the quaternary structure of proteins. Quaternary structure pertains to the assembly of multiple polypeptide subunits into a single functional protein complex, with interactions such as hydrogen bonds, ionic bonds, hydrophobic interactions, and disulfide bridges holding them together.
