|
What gives a protein its unique shape?
|
|
the unique sequence of amino acids in its polypeptide chain
|
|
|
the unique folding due to the sequence of amnio acids in the polypeptide chain
|
|
|
hydrogen bonding & unique interactions between the ‘R’ groups
|
|
|
all of these
|
Explanation:
Detailed explanation-1: -The amino acid sequence is known as the primary structure of the protein. Stretches of polypeptide chain that form helices and sheets constitute the protein’s secondary structure.
Detailed explanation-2: -The primary structure of a protein-its amino acid sequence-drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein’s unique three-dimensional shape.
Detailed explanation-3: -The complete structure of a protein can be described at four different levels of complexity: primary, secondary, tertiary, and quaternary structure.
