What is a polypeptide chain?

  1. A type of protein

  2. Long chain of sugars

  3. Long chain of amino acids linked by peptide bonds

  4. Sequence of DNA bases

The correct answer is: Long chain of amino acids linked by peptide bonds

A polypeptide chain is not a type of protein because a protein is a larger structure made up of one or more polypeptide chains. A polypeptide chain is also not a long chain of sugars as it is composed of amino acids, not sugars. Additionally, a polypeptide chain is not a sequence of DNA bases, as DNA codes for the sequence of amino acids, but it is not the actual polypeptide chain itself. The correct definition of a polypeptide chain is a long chain of amino acids linked by peptide bonds, which then fold and interact to form a protein.
