Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is responsible for specifying the 3D shape of a protein?
A
interaction with other polypeptide
B
interaction with chaperones
C
the peptide bond
D
the amino acid sequence
Explanation: 

Detailed explanation-1: -The amino acid sequence of a protein determines its three-dimensional shape. The structure of a protein can be described in several levels.

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: -Explanation: A protein’s shape is determined by the sequence of amino acids that make up the protein. The order of the amino acids, or the primary structure, determines the folding of the amino acid chains or tertiary structure. The image below shows amino acids along with their R-groups or side chains.

Detailed explanation-4: -Tertiary Structure of Proteins Tertiary structure refers to the overall folding of the entire polypeptide chain into a specific 3D shape. The tertiary structure of enzymes is often a compact, globular shape.

Detailed explanation-5: -Tertiary structure The sequence of amino acids of a protein determines protein shape, since the chemical properties of each amino acid are forces that give rise to intermolecular interactions to begin to create secondary structures, such as -helices and -strands.
